Finally took her out!!! But it didn't end well

Take a straight edge and put it along the bottom of your boat running fore and aft. Check that there is no gap from the transom to a few feet forward. I'm wondering if you might have a little cupping in your hull. (Cupping is caused by too short a trailer not supporting the stern properly so over time the hull actually bends down a little because of the weight of the engine). I highly doubt it, but since you don't have any tabs, and only one transducer on one side it's about the only thing I can think of.

I'll take a look at that soon as I can. I know for the past 15 years it was kept in a boatel and I'm sure they knew how to support the hull. But then again who knows and there's still 22 years before that something could of happened also. I actually dropped it off today to the fiberglass guy to finish the top off so I'll talk to him about it too. He will know what to look for.

What amazes me is the speed I read about from assorted posters......

If I read correctly, you recorded 49 mph at only 4,500 rpm with a less than perfect 200 hp outboard.

That suggests to me that full out / approx another 1,000 rpm you'd be around 55-60 mph.

Impressive.

That's according to a late 90's/early 00's GPS. But I did pull away from my dad like he was sitting still and his hurricane will do 38 or so. Not sure what prop I have yet. Never bothered to look.

I don't doubt that a 200 would push a V20 to 50 mph. My uncles V20 cuddy with an old 225 Yamaha is scary fast. Granted i didn't check the speed with a gps but it's way faster than my 22 footer.

Lean condition making more HP which melted a piston?
Maybe the tach is off?

Not doubting.......... I have a fine running Evinrude Etec 200 HO on my 96' V21, and it pushes to just over 49 with 3/4 tank......50 light on fuel. But that's at 5,600 rpm, tabs up, motor fully trimmed out on dead flat rippled water. Motor is said to produce 218 hp at the prop.
Some V guys reporting considerably faster which is amazing.

Again this is all off of a 15 year old GPS that was already in the boat. Not sure how accurate it is. Once I get her rebuilt or repowered I will get a more accurate reading.

Do you have a good Merc guy? Luckily I have a great one who loves older Mercs. He is in Gloucester down by Farm Fresh, off 17 a bit(I can give you his name and number). My 2.4 200 had low comp on 1 cylinder when I bought it. I didn't run it, took it directly to him to rebuild. Around $1500 later she was done and has been running her *** off for what 6 years now(7 maybe, I cant remember). This past Sat (best day of the soggy weekend) I was loaded with 3 kids, me, wife, cooler and 3/4 tank fuel turning 6000K on the way in the creek (racing a new-ish 24 Regulator) I got him, but just as I grabbed the throttle to bring her down....spun the prop. No biggie, just glad it happened where it did after I shook the rope at him!

Long story short, these old Vs love those old lightweight 2 stroke Mercs, maybe worth a rebuild?
