re-powing

[rsipe]

have available 1984 488 engine with compression of 170 on all cyls,new alternator, starter, new style exhaust manifold, and 4" cooler. transom asby with all new rubber and bearing, trim pump, and 2001 outdrive 181 ratio. all excellent in my opinion. reason for removal --redoing the whole boat, found mpi 4.3 V6 with transom and outdrive. the V6 will fit in the engine compartment and the engine cover will fit. you will have to fiberglass in the front engine mounts. If you decide to do V6 I'll be glad to help you with the size and measurements. my V20 with the 488 engine runs 40 to 43 mph and uses 7 gph @ 25 mph. [email protected]

I'm with Ferm, I'd rebuild your 3.7 or find another. My buddy and I both rebuilt out 170's for around 700 -1500 bucks, complete! Mine was already bored to .040 over so I replaced the rings, two pistons, bearings, gaskets, pertronics ignition and new head for around 800.00 dollars. My buddy's was original, had his bored .030 over, new pistons, rings, bearings, gaskets, oil pump, and head for about 1500.00 dollars. We both are mechanics so we tore down and reassembled both ourselves. They're very easy to rebuild. Both are running very strong with no problems. Find a good machine shop and do the numbers, you might be surprised. Its something you should consider.
