4 strokes on V20's
 

I'm looking at an 86'cc V-20 that needs some tlc. I would like to hang a 4 stroke on it when finished. Knowing they were designed for a 2s anyone have input on the additional weight. Is this advisable?

Thanks,
Bo

Keep it light is the general consensus. Avoid the V-6 4 strokes, and stick with the inline 4's. The YAMAHA 150-200HP 4 cylinders would be at the top of my short list if I was in the market for a 4 stroke to hang on a V-20. Followed by the 150-175 SUZUKI. The 140 SUZUKI will do the job as well, but a little more HP and torque won't hurt for those days you decide to load her down heavy.

what he said, in addition to moving the batteries forward along with knowing how to load your boat for even weight distribution and you wont have any issues. A new 200 yamaha wouldl be nice

I have run a Johnzuki 140 4 stroke for 11 year with good results.

Yammy F150 on a bracket on mine. The waterline dropped almost an inch but the boat performs much better IMO. Doesnt fly off the wave and holds a plane better in addition to a few other bonuses such as fuel consumption

I hung a 150 Honda on one back in '04...an inline 4 banger...was a little weighty, but such a sweet motor it was worth it...the Yams they're talking about would be the route I'd take these days...

Twin Yami 350hp outboards should work out - that's likely 1,500 lbs give or take.

Might run 80 mph before the transom breaks off.

Thanks for the input!

I'll be fishing Tampa Bay sometimes with 3-4 adults. Will the 4cyl. / 4str. be up to the task as far as torque?

Hey, your right in my neck of the woods. And yes, most any 4 stroke 4 cylinder will be up to the task with a good prop. Get a prop with alot of surface area to it, and you will have no problems running loaded down. I think the new YAMAHA 200 would be at the top of the short list if you can afford it, but even the 140 SUZUKI would do the job with good performance I would think. I know RANDLEMAN ahsn't ever really complained about his setup, and he runs a 140 JOHNZUKI on his cuddy.

Thanks for the info Therm. The 200 Yamy sounds like the way to go. I live right near Terra Ceia Bay. I launch into the Manatee River and fish Tampa Bay / Skyway area a lot.

The 150 Honda I used to have is for sale for a pretty good price...only problem is it is a 20" motor and I suspect you need a 25"er...See Classified Section if you're interested...

Thanks, but I'll definitely be going with the 25" transom.
Another question. Is there a difference in the overall lines between a 70's and 80's vintage CC V20? Any other changes?

Thanks,
Bo

I have had 6 people on board and pulled a skier out of the water with no problem with the correct prop.

I have never felt underpowered with the 140, which is probably the least powerful motor in this mid hp inline 4, 4 stroke class.

No. Most changes throught the years were in the layout of the cockpit, deck and hatches. The biggest change in the overall lines was when Wellcraft went to the V21 and added the engine bubble to the transom and at the same time went to the rounded glass side windows.

Thanks for the replies.

Good to know that a 140hp will work so well.

As for the lines question, I've heard people post that they like the lines of the 70's cc or that mid 80's were good construction years so it had me wondering.

Thanks,
Bo

Just remember that you asked about lines, and I answered as such. The appearance (lines) of the V20 stayed the same, however, the construction and the placement of various hatches, voids, etc underwent considerable changes over the course of production. :head:

I'm pretty sure the early 70's models had a flatter cap. Otherwise I wouldn't get quite so much wood for them.

Bo, when you say "CC" some think you mean Cuddy Cabin around here...I think yer referring to a Center Console...on the Center Console there were some changes over those year models you mention (and on the Cuddy as well). The floor deck was elevated making it self-draining and fuel tank size was increased...and in general (there were exceptions) the newer ones were 25" transoms; older were 20"ers. I liked the lines of the 70' models, but I'd opt for self-draining, deeper transom and larger fuel capacity 99 out of 100 times...

Sorry for the confusion. I did mean center console when I wrote CC.
