Hey all--

I already know what most of you are thinking, 'here we go again' lol :D BUT, I have already or are planning on making all the necessary mods; ignition parts, cooling parts, etc. I have done extensive research on the differences between marine and auto engines, and feel fairly confident that I've got most of the bases covered. I even bought and installed an AQ131 cam, knowing that the cam specs were different for the auto engine. However, the only thing I'm stuck on with this is the oil trap/cooler. It shows one in my manual, right beside the oil filter, but my block does not have any holes there to mount one on. How big of an issue is this, is it a deal breaker? Also, my manual as well as the Volvo website shows a motor mount underneath the engine, however, I can't see anyplace on the hull of the boat itself under the engine where one has ever appeared to be mounted. Once again, how big of a deal is this? Thanks to all for reading my post!!

is this a b 20 volvo? I have the same motor and there is no engine mounts on mine but my oil cooler is just on there around were the spot where the oil filter was. it is not bolted on i think it just slips on. It is very important to have an oil cooler you could do damage to the block or the oil could burn up

The 131's didn't use oil coolers.

Many of the 4 cylinder engines did not have front engine mounts. There is an adjustable mount on the transom shield that sits in a socket in the flywheel cover and holds the engine suspended.
Which drive/transom shield do you have?

It is a VP 275. When I go on VolvaPentaStore.com, it shows an oil cooler and related pieces being available for my engine......I've put a lot of money into getting this motor marine-able, I'm definitely a little leary on this......

It is a VP 275.

That is an outdrive.

Show me the parts diagram for an AQ131 that shows an oil cooler.

I apologize, I misspoke. The part I'm speaking of is an oil TRAP. I do believe you're right, there is no COOLER. Same question exists though :) As for YOUR question, what do you mean by what drive/transom shield do I have? I'm not following. :(
