marinizing an engine

Post by wolfie »

I have found a low mileage Volvo B18 engine, anyone got a heat exchange manifold and water pump for one ?

So what / how could i do it if i can not find a genuine manifold, thinking that i can do a bit of re plumbing and run it through an external exchanger, and run a external raw water pump via a belt system, build a "water" injected exhaust system and should be good to go, any one done this sort of thing before ? any pitfalls to watch out for ? any advice would be really welcomed.

regards

I'm not sure about your engine but on the GM block the marine one has stronger bearings as it runs on high revs a lot of the time it also has brass freeze plugs and I have to change the Alternator, starter, carb and distributor. You could try Barr marine http://www.marineengine.com/parts/barr_ ... /index.htm for your manifold.

Good luck with it :drink:

Hi,

From Memory the marine engine has a different timing cover and camshaft to mount and drive the water pump, so if yours is a car engine you might be better off using a belt driven Jabsco mounted on the front of the engine somewhere.
The manifolds are not cheap (i have replied in another thread) but not sure if you could do it any other way as the carb and exhaust are on the same side, unlike the later engine. I once had some Stainless manifolds made for a pair of BMW marine engines but they weren't cheap either, but again the carbs were on the other side, I dont think you would have the room to make a separate water jacketed exhaust manifold alongside the inlet manifold.
You wouldn't need a heat exchanger (closed cooling) you could just pump raw water around the block like most of these engines did (closed cooling was a factory option I think) however a lot of them ran oil coolers which had an adaptor where the filter screwed to the block (certainly on the later OHC engine).
Hope this is some help.
