Well, I've been working on getting my rebuilt 4.3 L back into my 1986 Searay & with several helpful suggestions I have overcome a number of difficulties.

My old engine had a mechanical fuel pump - the new one doesn't. Two questions:

1. What the proper placement of the fuel pump in relation to the gas tank. Does it matter if it is above the fuel tank - the only other option would be to put it down in the bilge -which doesn't seem like a good idea.


There is also not an oil pressure safety switch on this engine, which the installation instructions call for- there is only an oil pressure sending switch - single wire out the top. Is there something else to attach the hot wire to that would accomplish the shut off - or should I try to find a different switch.

Ayuh,...

The factory mounting point is in the same spot as the mechanical would mount...

You'll need to get an oil pressure switch,+ mount it in a "T" fitting next to the oil pressure sending unit....

Great - that sounds like an easy fix. I was pondering running a wire to the ignition but then read a post about the importance of a kill feature if the engine dies with the key still on. Makes sense
