    How do you all like your remote oil filter setups?

    I like them installed with the Flow going through the Filter the Correct Direction. 22yrs ago, when I bought my Boat, I had the Dealer install the Remote Filter. 2 Seasons later, at about 100hrs, the engine sounded like it had Mechanical Lifters. I happened to touch the Oil Filter nad noticed it...

    Mid1980's Mercury 2cyl 35hp Spark Plug Question

    While a lot of Oils(3rd Party) are said to Meet the TCW-3 Spec, that spec is over 30 yrs old. The Engine Manufacturers have Skin in the Game, and they know that if an Engine blows Up, throws a Rod, etc, People will cuss and swear at the Engine Brand, because to them Oil is Oil. I suspect the OEM...

    Random change in rpm at wot...BIG CHANGE

    Without knowing what the WOT Rpm is, you can't arbitrarily claim a sweet spot. You do not prop for a Speed at a certain/preferred Rpm, regardless of how the Engine Sounds

    1988 Merc 115 inline 6-Rough in low gear only after WOT

    My 1984 inline 115 didn't have a Low Gear. I wonder if the Idle Stabilizer was disconnected? I know a lot of People say to unhook it, but Mine never gave any Trouble, even after 14 yrs. My 115 used to get Stuck Floats quite regularly and would run crappy, but I could also see Fuel dripping out...

    Those are Water Inlets, for when the Engine running in Reverse. In reverse, the Prop is pulling Water Away from the Regular Water Inlets, which are on the Front of the Exhaust Snout

    1st Boat

    Because Evinrude no longer exists, I would pass the one with the E-tec, simply because the Engine is far less likely to be an Owner serviceable Motor, as in any Diagnosis, cause it is a Computer controlled DI Engine. The Older V4, which has a history of breaking Piston Rings, is a Simple to...

    J30JRSIE 30 hp Outboard - Carb Question

    Before you go ripping the Carbs off, see if you can get a replacement Orifice, install it and if the Problem(s) is solved. Might save you the Hassle of having to do a complete Link and Sync.

    2008 Volvo Penta 5.0GL Carb Problems

    That Power Valve looks like it was was exposed to Salt Water, replace it with one of the same Value. Just don't assume if there is one in the Carb Kit it is correct That carb looks dirty where the Air Bleeds are. The Accelerator Nozzles are in plain sight, under that Big Philips Screw When you...

    Engine Oil viscosity mixing?

    If Volvo specs SAE 30 Synthetic, they have their Reason(s). However, is the 25/40 syn a Volvo or Mercury/Quicksilver Oil? If so, I wouldn't hesitate to use it

    2008 Volvo Penta 5.0GL Carb Problems

    You really need a Book that describes and shows what the Holley Fuel Circuits look like.

    I know Holley used to put a Plastic, easy to remove, Cover over the Idle Mix Screws on the Metering Block. As for One Side Dripping Fuel, as they share a Common Fuel Bowl, is the Carb/Boat/Trailer Level?
