    1969 85hp starflite, low power and cutting in and out

    I retired 1yr ago after working 35yrs as an auto mechanic and currently still an aircraft mechanic! I can read and understand a manual. What do you mean by overheat horn? No reference to that in the service manual. Have i replaced the water pump? Not yet! But if OMC had a service bulletin to...

    1969 85hp starflite, low power and cutting in and out

    Something to ponder over! While putting my carbs back on the engine and trying to get everything reset i noticed when i turn the key to the on position the choke partially applies. I have a separate toggle switch for the choke and when i work that switch it applies firmly full on. I did a little...

    1969 85hp starflite, low power and cutting in and out

    All the reed valves are in place and a new fuel pump. compressions still 115 to 120. When the amplifier is defective, is it just no spark?

    1969 85hp starflite, low power and cutting in and out

    I did notice something that i just dismissed as a one time thing, but i find some water under the engine cover. Not much, just enough to notice. Can these engines ever have a problem with excessive exhaust back pressure?

    I removed the carbs and opened them up! They are very clean, high speed orifices are clean, all passages clear!

    The fuel tank in this boat is way up in the bow! The fuel pump is original, so i ordered a new one and will try it out. I will bring a fuel tank from my fishing boat that has the same connections on it and try that too. If neither of those things help, i will remove the carbs for cleaning.

    I replaced the dist. cap with a new old stock cap and wires when i had it apart. As soon as i push away from the dock and go full throttle it's not that its cutting in and out, it just fails to get to full speed( not full rpm). after a min or 2 thats when it starts cutting in and out and back to...

    1969 85hp starflite, low power and cutting in and out

    I checked the compression and all were 110 to 120psi. I checked the points and had champion plugs in it. I have switched to ngk and that didn't help. The engine just isn't getting to full power and then after a little bit it will start cutting in and out. Its like a fuel restriction or running...

    Msd ignition on a 1969 85hp starflite engine?

    I have 1968 Glasspar Avalon with a 1969 85hp starflite. I have read older posts about guys putting a msd box on instead of the original amplifier box. Has anyone recently done that same thing? I was having some mis-firings and completely dying out sometimes with the original ignition. So i...
