    Just acquired a 1957 evinrude 18hp

    Ok, got it dropped. The flywheel is not moving. The starter gear is clear of the ring gear. It's in neutral but I assume that doesnt matter with the lower unit off. I'm going to soak the pour some kroil through the plug holes and I'll report back in a week or so. Thanks for the help.

    Just acquired a 1957 evinrude 18hp

    Hi, I just acquired this motor. Paid $100. From a co-workers husband. He said he didn't know too much about it. It looks like someone was monkeying with it.

    OMC800 (1984) exhaust housing to gearcase shims - where do they go?

    I have about 0.040 between the exhaust housing cover and the gearcase (resting to lifting housing). Its supposed to be around 0.010. The manual (seloc pdf) says the shims are supposed to be placed under the ex. housing cover. When I bought the shims the parts diagram at the marine shop showed...

    OMC 800 will a 1981-85 outdrive bolt to a 78 intermediate housing?

    Pretty much stated my question in the title. I have a 1978 boat with everything original except the lower until and exhaust housing.

    Water in upper gearcase OMC 800 stringer ??

    I drained the upper gearcase last night and found mostly water in there. Where is it likely that water would enter? I was looking at the manual and it looks like the water pump pumps the water up to the upper gearcase and then out the sides where there are diagonal passages connecting to the...

    seized OMC 1978 5.0 (305) 800 - SOS

    Hi all, I'm new to this forum. After working on my boat yesterday, I was so blue that I could hardly sleep last night. I have a 1978 Seaswirl with a 185 OMC (GM305) 800 sterndrive. It was running fine although I noticed the starter was labouring. I was doing a tune up and after replacing the...
