Hello. I am new to the forum and hoping to find some info on a Chrysler Marine Slant 6 150hp motor that is in a old boat I just bought. The boat is a late 60s Silverline that came out of storage in CA and the last registration tag is 1978. The engine is mated to a Volvo Penta outdrive.
The motor is cosmetically in great condition and I fired it up very, very briefly to ensure it would start before I bought it but needs some maintenance to get fully functional.
I am familiar with the slant 6 as I had that engine in the first car I owned, but have some questions on the marine version.
I have posted some photos of the ID plate hoping someone can decipher it as to the year of the engine.
Also a photo of a housing that I believe is where a thermostat goes as there was nothing in there when housing was opened but the diameter is larger than the typical automotive thermostat, and the raw water pump that I know I will need impeller(s).
I initially thought the boat was a 1966 model as that seems to be the last year that this engine was offered as subsequent years it looks as though Mercruisers were the power of choice but the plug wires on the motor are date coded 1968 so I'm not sure.
Any info will be appreciated. Thanks in advance.
