So I got the manifolds off - Bravo III, 350V8
Here's what I did while I have great access to the engine:
- Check condition of manifold, risers, elbows
- inspect frost plugs, block
- Replace flappers, spark plugs, plug wires
- Replace all raw water hoses with wet-dry exhaust hose
- Compression test (190-195 all cylinders)
- Replace starter motor
- Install raw water blockoff plate (have raw water bypass thru hull)
Anything else you can think of I should add to that list? Almost ready to button everything up.
