Replace Engine...

[drexton311]

So I am thinking about replacing what appears to be a worn out 305 V-8 in my 1988 OMC/Reinell 185 F. I love the boat and it sure is in good shape, the motor just appears to be a little under powered, possibly due to the 110-105 PSI pressure check on the cylinders. But before I make a firm decision, I am going to double check timing, compete another pressure check, and confirm that everything else is right, so far I?m confident they are.
So I have been searching the internet for a good place to buy a 350 motor from. Does anyone have any good experience with a shop that can build a healthy 350 and be able to ship to Oklahoma? Another question, if I decided to go the Vortech motor route, besides the fuel pump and intake manifold, what other differences are there between my 1988, mechanical pump, 305 V-8? Am I correct in my understanding that the current exhaust manifolds will bolt to the Vortech heads?
As usual, thanks for the input!

Also, how do I determine if I have a standard or reverse rotation engine? I understand that I am supposed to look at the fly-wheel, but if I cannot access the fly-wheel, is there another method? Perhaps the rotation of the crank/harmonic balancer?

Your motor is a standard rotation. Your after 19
85, so you have a 1- piece rear main.

Plenty of places to buy a short block from. I personally would build one myself

When you do the next compression check squirt oil in the cyl. before the check. If the readings don't change you might just need a valve regrind,
