    150 Mariner ELPTO - normal & minimum compression?

    I have an mid 80's 150 hp Mariner elpto that isn't running as well as it used too so I'm working my way through it. I'm curious: 1) What is the "normal" compression range of this motor? 2) What would be considered the minimum compression before doing a ring job? 3) And if the compression on any...

    oil? in exhaust - 1985 150 Mariner ELPTO

    I've been having engine issues this summer (no power) so I did a de-carb...Holy Smokes!!! No pun intended but I'm surprised the neighbors didn't call the fire dept. I also replaced the plugs and was testing each cylinder for spark so I had started and shut down the motor a total of six times...

    V-6 Cylinder Numbering

    Just double checking. Are the cylinders on a V-6 numbered as follows: Top port side = #1..........Top starboard = #2 Middle port side = #3.......Middle starboard = #4 Bottom port side = #5......Bottom starboard = #6

    Does a gummed carb + 2-cycle motor = engine damage?

    A curiosity question came up the other day: If a two cycle motor with more than one carburetor, had one carb gum up... would running the engine damage the cylinder(s) supplied by the gummed up carb??? No gas = no oil = cylinder damage? Or is there more to it than that?

    9.9 Force (1994) Fuel Pump question

    I have a 1994 Force 9.9 (model 225.581996) that hasn't been started in years... I am just running through every thing and have a question on the fuel pump. I pulled the fuel line coming out of the fuel pump off. When I pump the primer bulb on the fuel line I get good flow, but when I pull the...

    Kicker motor on Cajun Bass Boat

    Has anyone mounted a kicker motor on a Cajun (or any other boat) with the 45 degree corners. I have a 9.9 I'd like to use on my '86 Cajun bass boat, but not sure how to go about it.

    Humminbird Wide Eye transducer ID?

    I have an old Humminbird Wide Eye (I guess old is redundent) with three transducers. The XTM-WS on my trolling motor, the XPT-6-24 in the portable case, and a third transducer that is a transom mount. It looks like the XT-WS but that unit says "not recommended for high speed use". The...

    Poli-Glow vs Penetrol vs ???

    I've acquired an old, extremely faded, glitter-flake finished bass boat that was left out in the sun for years with no maintenance what so ever. Well I've made sure the boat runs, the engine was gone over and brought up to speed, the electrical is ok (rewired what I needed to), etc. Anyway, all...
