I bought a 1980 vintage 20' bowrider with a Volvo Penta AQ 120B /270 outdrive last year. With such an old boat it seems like its always one thing or another that fails. The drive is great but the boat is slower than I would like at 25MPH @ 4800 RPM.
I dont have a specific problem at the moment but have just sorted though a failed tilt problem(thanks to old threads in this forum) where the electrical box had a crack and as a result there was some corrosion and rust. I was able to clean it up but would like to replace the relays with new ones just because the cases are in such bad shape. I ordered a set from from MPE but picked the wrong ones. I thought I would try going through my local Volvo parts dealer today and when he checked Volvo indicated that the relay was no longer available and there was no substitute. The relay housing is also unavailable.
Previously, I have replaced a few parts, alternator, etc and they seem to be generally hard to find and very expensive.
So my general question is simply, is this stuff just too old to try to maintain?
Another question is that I would like to have some more power( say 200 HP) and wondered what is the best outdrive fit for how my transom hole is cut for the 270? I think I have plenty of room for a V-6 in the boat.
Any thoughts or suggestions are appreciated.
