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.
