Hi All,
I purchased a 1990 Marlin Chinook boat with a bad 4.3 carbureted engine. There is water in the oil, and a rod knock. It has a good DP-A drive in it, but repairing/replacing the 4.3 was getting costly. A 190 Hp 4.3 on a 4000# boat is probably going to be under powered in any case. I contacted the local Volvo Penta dealer, and they only suggested replacing the whole package with a new one for 17K.
I found a 2000 5.0 Gi package with a DP-SM drive complete for what it was going to cost to repair the 4.3. The engine is complete, has good compression, and appears to have been loved by its owner. This puts me ahead with fuel injection, and 250? HP. Except for the transom, it should be a bolt in job. While everything is apart, it is a good time to replace some seals, gaskets, and hoses. I am no expert on outdrives, but I would imagine that it could use some love, new hoses, bellows etc.
My question is that I see that there is an adapter plate made by VP to go from the 290 cutout to the DP-SM. They also make one that is to adapt a DP-A to a 290 cutout. I thought that the DP-A used a 290 cutout? At $800 for the adapter, this is not something I want to trial and error........
Thanks in advance,
Doug
