Chrysler/Force are old school designed engines and very easy to work on.
They were designed in the 60.s and 70.s, the only big thing which was up dated was the ignition systems and the piston design .
Before buying check compression and spark at all 3 cylinders.
Does not matter of brand, always check compression and spark.
If it is possible, run the boat in water and check how it perform and the cooling system,
Remember Chrysler/Force do not have a telltail as OMC and Mercury.
They have idle relief holes at the back of the midleg.
The weak thing on Force 3-4 cylinders are the piston rings, the top ring has very little land to the piston top.
They tend to break and score the cylinder walls.
The 3 cylinders has three carbs, one feed each cylinder.
If a carb get clogged or running lean the cylinder will score after a while.
