Very true. but this is how it will work for me....
I'll buy the shims and bolts, unbolt the engine, install,
SOME OTHER CRAP WILL HAPPEN, the condition will stay the same and I'll still need a different pitch prop.
OR
I'll buy and expensive as hell 4 blade, easy one nut installation,
SOME OTHER CRAP WILL HAPPEN, whatever pitch I end up buying will be the wrong one no matter how many seasoned old salts agreed that it was exactly what I needed for the application, the boat will STILL porpoise.
