Hello all, just a couple of Merc 4.3 questions.
What is the difference between the two besides the 4bb carb?
Can the 1990 be mounted in the same position as the 1995?
Thanks in advance.
.one is 5 years newer. other than that, the 1990 is pre balance shaft, the 1995 has a balance shaft. they can be mounted in same location, just use the correct motor mounts for the correct motor.
are you looking to replace a bad 1995 with a 1990? If so, look for a 1993 or later to get a balance shaft. you can get a low mileage long block from a u-pull-it salvage yard for under $300
I believe the 95 is a Vortec
Ayuh,... That's '96, 'n up Rick,.....
You will have to verify the Vortec in 96. It was a crossover year for boats. I would for sure look for a Vortec.
Thanks for the info, will the Vortec fit in the same mounting positions as a pre-vortec 4.3?
The assembly will fit both.
I got a 1988 Merc 4.3 for $100 so i can switch over the parts.
Ayuh,.... Yer picture appears to be a Vortec motor,...
The intake manifold, 'n mechanical fuel pump from the '88 won't fit the newer motor,....
$2700. sounds pretty high for that work, why not do it yerself,..??
The boat has no engine or out-drive, just the transom assembly for an Alpha 1.
would a 1998 5.0 MPI fit in the transom assembly that a 1995 Merc 4.3 used to be in?
