Ok I am about to undertake some major upgrades on my 14' center console semivee. It currently has a 1978 70 horse on it and it is just not running the way I want. I have shimmed it, sharpened it, new coils, just about all I think I could do to it. I am tired of it so I have got a new/used outboard I am going to use to repower my boat. It is a 1989 70 horse. It is the bigger block which Member lil blue rude told me is the way to go. After pricing everything out I am debating a coupel things. First the compression is a little low for this motor. All the cylinders are right at 105lbs, which the top cylinder is the worse. I have pulled the head once and noticed some light scratches but everything else looked fine. The rebuild of this motor is going to be up near the $600 range, and for the new shaft to match my old pump up to the new motor is $170. This was ok, but outboardjets in California is telling me I should get the new bearing and housing with the new shaft for $400 for the complete assembly. My question now is should I go ahead and get the new assembly and just run the motor and see how that works out. Or should I try to break my budget and overhaul it completely? I would not worry about this but I have a fishing tourney lined up in October and I don't want to be stranded with my fishing buddy looking like a fool. Any advise is appreciated. Also I had a question about once I am shimmed out on my impeller which should I purchase first, the impeller or the liner? Does one wear out before the other, or is that something I should replace both at once? Thanks again. I will get some pictures up of the boat tomorrow so you see what I am starting with.
