    Water in the oil 1985 Searay 454/340

    Are the engines fresh water cooled? If so check the coolant level. If the coolant is full then it might just be an exhaust manifold riser. I they are raw water cooled it could be plenty of things. Since you are a mechanic pulling the plugs as you said would be the first place to check.

    If the engine had not been started for a period of time before the service it could be a compression problem. A weak cylinder will smooth out with increased rpm.

    Is my shifter installed right?

    You have it right. It is normal for the propeller to “ratchet” when the drive is in either gear. If it did that in neutral then the shift is not splined right.

    Mercruiser 5.7L Black Scorpion grinding noise when in neutral

    The slave solenoid is under the cover. Look for yellow wires with a red stripe. The other place to look is where the ignition switch is. At one time Mercruiser ignition switches had a problem starting the engine without the key turned. Since the starter only activates in neutral I think the...

    Coupler failure

    I have had quite a few customers who had damage from submerged objects always was able to help the customer. Has the drive and prop been inspected by an adjuster? If the damage is less than your deductible then you are out of luck. Just be sure to have the shop check for any additional damage...

    Volvo Penta 305 - Squeak and Rattle

    I suggest starting the engine and let it run until the noise is heard, then remove the belt and restart it if the noise goes away then it has to be belt related. Running the engine for a moment will not hurt anything with the belt off. If the noise returns then you better get the boat on the...
