1959 Alumacraft Deep C with a Volvo Penta engine

[EO123]

Hello,

I'm trying to help my nephew locate some engine parts for his 59 Deep C. It's a great looking boat but need some engine repairs, it has a stuck valve, needs a water pump, and????:facepalm:

If anyone can point me in the right direction it would be greatly appreciated.

I searched on line but didn't come up with anything other than 1959 was when volvo penta introduced this setup.

Thanks
