we had the same motor on our mako 226, would jump out of the water..

Definitely rebuild the carbs, had an 82 black max 150 ran rough when I bought it. Rebuilt the carbs, thing was a beast. until a buddy borrowed my boat and ran without 2 stroke oil.

[@eltigredetejas2328]

Same 🤦🏿‍♂️ never again …they went tubing with mine

[@TheKing-nu4fk]

Wtf? Who would let someone borrow their boat?

[@brandonh4832]

So rad watching this series!

When the engine was running, it didn’t sound like it was running on all 6 cylinders, do a compression and spark check first. Then go from there, no need to put a lot of work into an engine that may have a “ bad “ cylinder .

Appreciate the feedback. Did both of those 120-125psi on all 6 cylinders, new plugs all around and spark on each. Im convinced it is something to do with one or all of the carbs. Gonna clean each out.

The V20 was one of the best hulls Wellcraft ever made, a lot of people were very upset when they stopped making it. A great rough water boat that I fished off the coast of NC. Only drawback I ever found was it had a 60 gal. fuel tank and it could have used a 100.

Appreciate the information, I really wanna get this one in the water to see how it handles. Just have to finish troubleshooting mechanical issues.

The gas on top the water that came out the tank is ethanol free because the water mixes with ethanol and the pure gas is on top

[@sharpdetailing6001]

I would of put fresh gas in her not use the old gas that had crap in it

[@ianmcculloch383]
