Well, FIRST: Does your Lazer still have a capacity plate? If so, it is rated for up to 150? If it is rated for 150, the Force 150 is a dual exhaust engine meaning that it has an exhaust snout AND exhaust exits through the propeller too. It is a decent engine BUT there are a couple of possible problems. 1. ALL Force engines of this age used a semi-keystone top piston ring. These rings frequently do seem to carbon up and catch in the exhaust ports, breaking the ring. The fix is relatively simply in that it usually doesn't require a rebuild, but it does require a new piston and ring set. 2. Occasionally, when used in racing, they did break the crankshaft. Being used in a bass boat, I would say you are using it similar to racing--let's face it--no one in a bass boat is going to idle or even cruise to the fishing grounds.
Without question, run a compression check on all 5 cylinders before buying. If any cylinder is lower than 100, it has a broken ring and you should dicker for quite a bit less.
Other than these two weak points, the engine is decent. It is simple and easy to work on and uses a 50-1 fuel/oil mix which means you don't need to worry about oil tank level or oil injection unit going bad.
If you get all the controls and if the engine is running well, then 1000 bucks is not too bad. My partner and I would be selling one for about 1500. AND, I usually pay around 200-300 for one with broken rings. Hell, the lower unit alone is worth 300 and the tilt/trim is worth 400 if you were to part the engine.
