Thread: SPEED HELP

Some of the duck guy should be able to help they seem to get the top speed out of their motors

Look up "Arkansas tiller handle outlaws and performance boats" on Facebook. They're all about getting the most speed. Depending on the model of 40hp, there's quite a bit you can do to it.

Yes sir! Hahahahaha

If i recall thats the 59 cubic inch mercury model which is a 3 cylinder 40/50/60.

If so i believe you can still buy 60 carbs - easy install. If it were mine i’d do that and delete the oil injection. Then if you need a prop get a yamaha black stainless and tweak your setup a little.

You’ll be faster

My Tracker 175 and a 50 merc got 30mph fully loaded with a partner and 32 light with a 4 blade 13 pitch trophy prop. There isnt much you can do with those little motors without tearing into them adding more compression with cut heads, porting and larger carbs. By that time you could have traded engines and maintained reliability and longevity. There is a splash baffle you can remove from the cowl to get more air in, but to actually get some real gain, you need to rejet the carbs to give more fuel to produce the addition power, and even then you might get 1-2mph? Enjoy your reliable engine, even though it may be a bit slow or step up to a 50 or 60 horse.
