View Full Version : Hard Core - Drive Ratio Question

06-18-2010, 12:04 PM
Hi All,

Your cigar buddy with a general question -

What do you think of the idea of switching a drive from the original 210 to 260 hp / 4.3L Chevy / 1.86 (omc) gear ratio to a 1.55 (merc alpha 1 gen 2) driven by the same 4.3L -

(my understanding is that the 1.86 is the correct gr for the v-6, and the 1.55 is actually for a 350 v-8) talking about the 2 gear upperset, not the 3 gear lower set)

What would be the consequences of this, the implications, how would you prop this setup? Will the engine have enough hp to drive this setup? Could/Would this be damaging to the new engine? (v-6)

Thanks In Advance, Please advise, as many of you know this boat.

it will be a pooch!,chitty acceleration (wont get to speed as fast) and may loose the snappyness in the boat + alot of rpm's
