BMW B220 Marine engine first run

[@Spar09]

Hey gr8 work! I got the exact same setup on my boat. Got problems finding spare parts in sweden tho... you dont happen to know a shop with marine bmw parts that ships worldwide?

It sounds like the raw water pump is not pumping water adding to the exhaust note. Could need a fresh impeller or have some obstruction in the exhaust manifold or a break in the suction hose from the leg through the transom shield. Also the idle speed sounds low and that could be due to a malfunction in the TN choke which should bypass the throttle while the engine is still cold and initially cause the idle speed to be about 1200 while the engine comes to temperature.

Hello! sorry for the incredibly slow response. I only just figured out that there were comments coming in. I am better with outboards than I am with KZbin. Thank you for your detailed response. I will definitely check everything that you have mentioned carefully. It sounds like you are quite familiar with these units. Any and all advice is GREATLY appreciated. Cheers

I have 2 of these in a Sea Ox walk around I am getting ready to re-build... the boat, not the motors. When I bought it, the motors only had about 100 hours on a full hual.

Hello! sorry for the incredibly slow response. I only just figured out that there were comments coming in. I am better with outboards than I am with KZbin. I have been working on this one for some time and hope to have it ready for the water this spring. I would love to see your Sea Ox. Do you have any videos or photos posted anywhere? Cheers
