1983? -75hp Chrysler

[Crazyman1225]

This is for sale on CL , the guy says he can't get spark, or hasn't checked the compression. Previous owners son said it ran two years ago and has been stored in a garage since. I would like to know anyone's opinion on these motors? Are they somewhat decent and reliable, or are they junk? I can probably set it up to do a compression check, but am not sure what might be the cause of no spark. He has a service manual and parts catalog to go with the motor. He is asking $450 for it, is it a grabber or should I stay away from it?

if the compression checks out , go for it but i wouldnt pay more than 300, good simple to work on motors, and lube the cylinder before testing comp, because it been sitting awhile
if its been run in salt water i would avoid it

Every engine advertised on ebay and Craigslist ran when put into starage. Definitely do a compression check. If it is ok then consider buying the engine but be aware that while easy to install, electrical ignition components can cost a bit--adjust the price accordingly.

Thanks for the advice about the motor, guys. I was a little leery because of it being made by Chrysler. One question I have now. I can understand about shooting a little oil in the cylinders to lube them due to sitting for a while, but doesn't that give you a false compression reading? I know that the oil trick on small gas engines will change the compression reading, and at times create enough compression to even make it fire? I only ask this because of not being familiar with outboards at all. Thanks

Usually squirting oil in the cylinders will increse comp.But the comp on an outboard should be within 5-10# of each other.If it has a bad cylinder it will show even if you squirt oil in it.My Force has 150# on eachwith a good guage.
Look at the plugs first.They should have NO rust just carbon and burned oil.
$450 is too much even if it runs.J
