Ok....Here is one for those with lots of engine experience.......Please.....I recently started my Yamaha F150 and the engine smoked (Heavy Blue Smoke) for about 3-5 minutes and discharged oil into the water from the exhaust. Same thing on a second start up 10 minutes later. This new Bennington has only 40 hours on it's first season Tamaha F150 engine. It was carefully broken in with varying RPM and had a number of max RPM's after the 20 hour oil change. The engine had several days of pulling tubes and kneeboarders....it had a good solid break in period. The engine has been perfect until we tried for one more trip out and wham......huge smoke and oil discharge. I have been boating for nearly 40 years and have all the experience that one needs to know how to trim the boat and take care of the engine. I however am more of an inboard/outboard saltwater guy and would like some advise. Why would I get so much blue smoke at start up and an oil discharge? This is not a puff or two but, enough smoke to look like there is a boat fire in the marina!! The dealer tells me that the compression test is OK and there are no obvious engine issues based on the computer.... BUT....the smoke and discharge was huge....something must be wrong. It looks like a ring or piston issue to me but, the engine runs smoothly. In looking online, some say that if you do not store the engine up slightly there can be oil that leaks into the cylinder head. Others swear by storing the engine at the dock full up position. Not sure I understand that???? HAS ANYONE HAD THIS ISSUE WITH A YAMAHA F150 i=in smoking and discharging oil at start up? What advice from fellow outboard owners do you all have in terms of storing the engine in a down, up, half up or full up position. I am waiting two weeks + for the Yamaha etc to come and check out the engine.....It would help me if I know about some other experiences......Thanks guys....
