I am thinking of changing engines in my boat from 3.7 liter 4's to 4.3 V6's. My 3.7's need to be rebuilt this winter, and I estimate it will be about 2,500 each to have them done completely, if I pull and re install them.
Doug Russel sells "certified" rebuilt 4.3's for about 3,500 each. I am thinking about just upgrading to these more powerful, smoother, quieter, and MUCH easier to maintain engines. There are also lots of parts available for them and my 3.7's are really hard to locate parts for, and when you do they are expensive (1,300 for an exhaust manifold, 500 for a distributor).
There are a couple problems though that I need advice on. The marina mechanic tells me that the new engines will work fine with my outdrives (which were recently rebuilt by the PO) but the boat needs new stringers because the new engines will mount differently. Also, I am wondering about how the wires will all hook up to make the gauges ect. work properly. Any idea on how hard it is to install new stringers and what type of cost I can expect? Also what will it take to make all the wiring work?
I am not sure I am going to take on the project, but you really can't decide until you know the cost and time needed, so I appreciate the help and advice.
