    Bolts for water pump are rusting

    Wire brush them and paint them with black rustoleum. likely the paint on them got nicked off when you changed it. What you are seeing is typical of many areas on my engine that is also fresh water use. My boat is a 2004 but I did a repower in 2016 so everything was painted fresh then. a number...

    Raw water pump 7.4 454

    you need to get the cam specs first. Dont mess around with it as it will ruin the motor fast of the exhaust is wrong. Even if you have to pull the cam to find the number on it it is worth it to do it right. here is a basic write up on it. Height of riser is not the issue but length where...

    Leak into bilge, bellows?

    would assume what you are seeing is either previously mentioned grease build up or maybe some burrs on the splines on driveshaft or coupler. the whole thing is way less precise than some make it out to be. what you describe adjusting up and down only making it worse shows you got it as good as...

    lifter issue and rock arm registration

    If you cannot get the tool easily in Italy - not as elegant but you can also put in the distributor as is (need intake bolted down) and turn the engine over with the starter to prime it, leaving spark plugs out.

    Leak into bilge, bellows?

    funny you mention cleaning the grooves. on machinery at work when having to reuse an old oring that is compressed... years ago an old timer showed me to put vaseline (food application) or grease in the groove to add some thickness.... Thought he was FOS but it worked

    Leak into bilge, bellows?

    Leak into bilge, bellows?

    a couple of things that have hung me up when almost all the way in - the orings on the driveshaft- are these greased up, and when I have been doing alignment work one can build up a lot of grease in the coupler and take some effort to squeeze out. Did you check the alignment i ok? While it...

    Upper gearcase pinion bearing replacement

    If you change the bearings and races you will need to set up rolling torque and reshim the gears. Slide hammer on jaw puller will get the races out. A little heat on the housing helps

    Leak into bilge, bellows?

    yes normal to have to center the bearing by whacking the adjustment tool in 4 directions (i think this is in the manual), and adjust the alignment after doing a gimbal bearing.
