Went and pulled a 1990 Force Outboard 50 model 507X90D, from a 1990 Bayliner boat yesterday for a pretty decent price. Got the steering, throttle, all cables, plus the electrical all the way to the battery with the deal. It hasn't run for three years. But was running when the guy we got it from purchased the project.

Checked compression and spark before we started. Both cylinders just over 140lbs compression and sparking on both plug wires.
We plan on putting it on the fishing boat we are building from the hupp up.
Ordered carb gaskets and a new needle. I'm sure the bowl is varnished and want it fresh/clean before we try to fire it up. Will install a telltale while I'm at it.
A new impeller is also on the way as well as new spark plugs. The old plugs look new and we can keep them in the boat box when we finally launch, as spares on the lake for 'just in case'. We will hopefully have it ready to launch in November.
When the parts arrive will be getting started to ensure the engine and drive are sound. Hopefully things will go smoothly.
Can't think of anything I'm missing on getting it ready for install in a few weeks. Fingers crossed...
