Etec 200 HO engine height
 

Took a good look today - cav plate is UNDER the water on plane with the exception of fully trimmed out max / WOT - then it's above water.

Genie Ayre - how does that compare to your set up ?

I'm planning to raise TWO holes - that's about 1.5" -2" and re test speed and overall performance.

I don't know anything about the build of your engine, but I wonder where the water intake(s) are on it. Will raising it up that high put you at risk of no water intake at high speed? Just something to think about.:head:

Mine was lined up with the bottom of the boat-- I raised it--look at picture. No issues with turning or ocean conditions creating cavitation. Mine was underwater too--no longer. sorry about the pictures

Doesn't look much higher than mine - thought I'd see it way up on a jack plate LOL.

Difference is we have different transoms, yours is going to be deeper in the water than mine to start with--mine got moved up to holes from where it was mounted--cavitation plate is now where it should be in the water. You trim enough up and you can make any engine cavatate.

With your engine down all the way, how much higher is your cav plate from the bottom of the hull ?

Bennett, I have always read/heard the cav plate should be 1/4 to 1/2" ABOVE the water's surface when on plane and properly trimmed...which will most likely mean trimming down in turns, which is a normal expectation anyway on a properly mounted OB...

Reel - I'm beating this topic till there's nothing left to discuss !

But I can report I've learned some things by doing so........

Since my cav plate is under water unless at max angle trim, I believe reasonably safe to
say I can go up 1.....maybe the 2nd hole too.

Plan is to do so on Tuesday - and re test all aspects of performance including turns, and WOT speed.

While I talk " top speed " for fun........as I've posted, I consider it a matter of maximum efficiency too. If a boat runs 46mph, and a few adjustments yield 50 mph, then it's likely more efficient across the board.

From the pictures you posted, I would start with two holes up, three if you could. Normal recommendations is you want to set the anti-ventilation plate up one inch above the boat bottom for every two to three inches back. The built in setback on the V21 should allow you to put the anti-ventilation plate at least an inch above the bottom of the boat. you shouldn't have to worry about any water pressure issues unless you put a jack plate on the boat and really set it high. Go ahead and set it higher than you think you need it, if its too high, you answered your question, if it runs good there, then you will always want to know what one more hole up where it needs to be.

Beat on!!..I don't think peeps in general pay close enough attention to this setting and are too afraid of not gettin water to the engine...I agree w/you...EFFICIENCY is the goal, not only for speed consideration, but fuel economy and others as well...Spare is right...w/the 21's setback, you'd have to jack it outta sight to get it too high...

Iffin you want it to fly raise the motor and trim it out with a light load. if your bottom is straight it should see 50 plus with that 18p. How many hours on the powerhead? Maybe it isn't broke-in yet.. It will come.. :nic:

Motor checked out and runs great. Got lucky - 05' with about 275 original hours, 70% of it at under 2,000 rpm. The computer print out can't lie.....it is what it is..........

Plan is to raise motor tomorrow if weather permits -and re test.
Thanks Reel, and others for your suggestions and input.

There is no break in on the E-tec motors--so stated by Evinrude.

There is no break in period like olden days where you had to go out and do 2 hours idling, then 5 hours of keeping it under 3500-4000 while varying the throttle, then varying the RPM's with short bursts to WOT for the next 3 hours. But ANY engine WILL loosen up some after it is broken in. So there is a difference between break in and broken in.

Etec starts nearly instantly, and idles as if it's warmed up nearly instantly too.

No smoke, quiet, smooth and powerful......shifts smoother too.

So, I understand how / why they position this engine as an option vs 4 stroke.

Can't beat the torque of 2 stroke though.

Well then--lets say worn in--not break in as the old days.
Mine runs the same now(800hrs) as it did they first time I ranit and hammered it:hi:

Ran a little more " serious " test today - engine at same / current setting, two holes from highest.
This is with the bimini top down, approx 82 degrees, 72 degree fresh water temp (del river)
This is from running with tide, then against, and recording the exact mid point speed.

Engine down all the way - not trimmed out:
3,000 rpm 19.6 knots
3,500 rpm 24.3
4,000 rpm 29.1

4,500 rpm 32.9 with 1/2 trim
4,500 rpm 37.0 trimmed all the way up for max performance
5,000 rpm 37.4 trimmed out 1/2 - 3/4
5,700 rpm 42 knots trimmed out to the max speed on gps
5,800 rpm 43.5 knots running with the current and trimmed out to the max ( 50.02 mph )

Additional comments
Cavitation plate - mostly under water, even with light to medium trim out at all speeds.
Cav plate is out / clear of the water with engine trimmed at maximum .
RPM - able to hit proper max range with full trim WOT, suggests current 18" Rebel is not too big.
Fuel - between 1/4 and 1/2 full.

Tomorrow - raising the motor 1 hole for sure.........and maybe 2 for the highest setting.
Then re testing on the Del River at each speed to record, compare, and check cav plate position, water pressure, intake position etc.......

waiting to see new numbers--Still alot of rpm compared to me--at 4200 I am around 41mph. and at 5300 trimmed out I am around 52 with no wind and flat water. 19 pitch. I do not want to run in the 5700 rpm range--just me.


waiting bennett

Now that I'm hitting 50 mph, fine tuning from here. That, plus not in a hurry to go back to ramp on Delaware River where I had light cover stolen from my trailer. Continuing " experiment" at leisurely pace.

Fished the ocean yesterday, running mostly at 3,000 - 3,500 rpm where these etec's sound like they're just idling along.
Ocean very rarely flat enough for top speed messing' around........
Thanks for all your feedback Genie, appreciated.

Awesome, sounds like you are a happy camper now. Glad I could help ya out, some how--lol.
Now save up and get that I-command gauge.
Enjoy time now.

How is the fuel burn---happy with it?

No idea of fuel burn - just have the fuel tank gauge, but............seems to use less than previous 150 carb motor, especially in the 3,000 - 4,500 rpm range.

Congratulations on the 50 MPH mark. I knew it was in it. :beer:

Thanks but I'm humble considering your 61 mph V !!!
Wow, that's dialed in and flying along. You must have that engine, prop, trim, all perfectly set.

I haven't re tested since moving the engine up 1 hole, but eventually.

Rode fine at 50 mph.

Up the one hole - same top speed.

What prop are you running now, the 18 or 17? And a rebel--right?

May stick with the 18" Rebel because it seems to run fine, and to the proper top rpm range.
I may raise to the last hole to compare performance, but either way, it's running well.

60mph is the new 50mph. Your in old times. Better speed up or get left behind.....

I agree...........when I was a little boy, a typical run about, fishing boat that ran 30 mph was considered good speed. That was when the biggest outboard motor was rated at 125 hp or so. Then later, our 21' T-Craft with Merc 140hp ran over 35 mph....felt fast.

Then 40 mph was a " standard of decent speed"........now any given newer dealer rig runs 45-55 mph, no big deal.

These V's were based on running into the 40's.....not really above 50mph.
At my current top speed, the V21 rides fine, no wiggle, no chine walk, just straight and even. What does that mean ??? That means I'd really like to have a top speed of.......................... 55-60, but that's it, not faster because I believe it would be a dangerous boat at that point.

You had a T-craft? Those are really cool hulls. Wide, stable, but absolutely flat at the stern.

Ridge - you're the first and only familiar with the T-craft that I know besides me.
Very similar to the V in style, appearance, and ride. The flat taper to the stern didn't make it pound any worse and it was very stable on the drift. Hull was very strong and dense - it was a well made boat. We still have pictures which I could maybe scan and send so one of you can post. T- Craft boats were built in Titusville ? Florida hense the name. Ours was the 20, or 21 I don't recall, seemed as big or slightly bigger than my V21, with huge cockpit and cuddy under the bow. Our family used it for fishing and cruising Long Island bays. It had saddle tanks on each side, 20 gallons each, 40 total as I recall. Very pretty boat too.

T-crafts- I know of a fish guide that customized a 24' Center Console for double duty inshore/offshore. He was running some hopped up Yamaha 250 on a full transom and a paralift bracket. He ran a low water pick-up and a big prop, he could jack it to the moon and run shallow with the flat bottom it did real well. It floated on top too. I liked it, it had 3/4" plywood for the deck and new stringers it felt solid as a rock.. Boat worked well offshore in the gulf too. There was a 26 Center for sale up near Homasassa recently, it was a I/O with a T-top. So I know of three near Homasassa. The other was a cuddy/hardtop painted yellow and towing boats for a living. That says something about the toughness.

Close friend of mine has a 24 T-craft. It's not the flat bottom one the flats guides like in Fl though. It has a small v berth like our V20s a hard top pilot house and a big wide cockpit for fishing. His has a 350 small block with a volvo penta I/O. It has a decent entry, but not quite as much deadrise at the stern as our V20s. Bgreene yours was probably a 21. They looked very similar to a V20. Some came with twin I/Os for power. The "T" stands for the owners name which was Thompson I believe and they were manufactured in Titusville FL until the factory burned down sometime in the early 80's. Old T-Crafts fetch a lot of money due to being highly desired. A lot of charter captains around Savannah used to run them in the 70's and 80's. The flat bottom 24 Ridge is speaking of is so versatile can be set up for flats fishing with a 250 on a jack plate or shrimping with an inboard diesel.

I'll try to find some pics.
