Hi - I have an old whaler with a 3 year old Yamaha 50hp that we use to fish and kick around in.
A few weeks ago my teenagers were using it on the lake and it started sputtering and an alarm went off. They were able to sputter back to dock. It has an above deck gas tank that was full of water. Not sure of a crack, unseated cap or a leak in the fitting but it was 1/2 full of water and that water quickly overwhelmed the secondary and primary water separators. Easy fix (replace).
I drained everything, replaced filters, hooked to new gas and after some long cranks it fired, ran rough for a bit then smoothed out and ran like normal (all on a hose in the driveway). Thought I was home free until I checked the oil…. Chocolate milkshake.
I have drained oil and replaced filter (2x) just to get the water out and ran on the hose for about 20 minutes and the oil has stayed clear. But we must have blown a seal somewhere while running on gassy water to end up with it in the oil right?
Seems to me I have an expensive trip to the shop ahead but I thought I’d check to see if anyone wanted to tell me I had nothing to worry about first! If not who’s your favorite Yamaha mechanic between Seattle and Anacortes…
