    Prop hitting anode

    I remember in 2018, I found a lot of TP props where one of the three was distorted. It was like if Wax had been used in the Production, and had sagged.

    Are you mixing the oil yourself, or does your engine have one of those Autoblend oil premixers?

    1980s mercury 115 tower of power issues!

    The Decal is post 85, could be 86, 87, 88. Serial # would determine which I doubt that pump is USCG Legal. It might produce too much Fuel Pressure and that is Overloading the Floats and Flooding them. Poor location for Pump, places fuel hoses/wires near the Shift and Throttle Linkages...

    1985 evinrude 30 hp prop power issue

    If you had performed the Link and Sync correctly, the spark will be fully advanced and the Carb fully opened, however they don't move together much. Almost all the Spark Advance will happen before the Carb opens even a bit, then after Full Advance occurs will the Carb open fully. A good Service...

    Help with 1995 9.9 Mercury sailmaster, they are all long shaft or long shaft +. My issue is getting shift linkage correct

    If the it had a Rotating Shift Shaft then what I had said, could apply. However if it has a Shift Shaft that goes up and down, then ignore what I said. Spinning the Prop Clockwise in Forward, should give a Click Click Racheting sound, Counterclockwise should produce a Clunk, and no more...

    1991 20HP Evinrude no acceleration

    Pull the Plugs. 40 yrs ago we had a 25 behaving like that. After going thru all kinds of checks/tests, we plug the plugs. We found one of them with something, likely a bit of Carbon, bridging the Gap. Removed it, put the plugs back in, and all was good. I doubt that engine has a "Slow Mode"...

    Help with 1995 9.9 Mercury sailmaster, they are all long shaft or long shaft +. My issue is getting shift linkage correct

    Are you sure you are getting F-N-R with the engine off? How did you verify it? If by chance you managed to misalign the upper and lower shift shafts, you might have F-F-N

    Does my outboard have a thermostat.

    I think the 2 cylinder 400/402 was the first Mercury to have a Thermostat. In 73 the 3 cylinder 65hp got one too

    Prop hitting anode

    Either a bent Propshaft, or a Blade with the wrong geometry. Some 3rd Party brands are famous for "One of these Blades is not like the Others, one of the Blades just doesn't belong..."

    Trailer questions for vintage Glastron Tri-hull

    Look the Outer Rollers on the Transom, they are unable to pivot as to lay flat against the Hull. I took those pic 10 yrs ago, and he no longer has the boat, so I can't take any more, but I do remember the outer roller had a very small contact area

    Engine Bogging Down When Cold

    If it is preventing full power when not up to operating temp, how is that bad? In reality it will keep the engine from dying a premature death
