im installing the starter on a 4.3l v6 after fix the broken screw and a hard work removing the old screw (i have excellent tips to do it i'll post them later)

its recommended to ad anti-seize to the new screws?
or that can cause the screw to fall.

Re: screw seizing

Personally i have been a big fan of plenty of anti-seize and a very small drop of locktite blue on a lot of things

somewhat counter intuetive - but it keeps the screws in place (like a locknut, or lockwasher) but then also keeps the threading in good shape and corrosion free.

Ayuh,.... Ya mean lock-Washer,..?? Don't do that.....

Use fresh Mercruiser starter bolts,...
They have extended, smaller heads, for wrenchin', 'n the proper knurling...

Use Quicksilver perfect seal, or form-a-gasket #2..... then tighten to 'bout 35ft.lbs.

Re: screw seizing

Chasing the threads w/ the correct tap and die prior to assembly is usually a good starting point.

Using Loctite on threads is a great selection for many fasteners. Every single time I use Loctite the fasteners look brand new at disassembly.

Many of my engine room fasteners have been replaced by me to the McMaster-Carr ultra-corrosion-resistant Grade 8 fasteners. The finish on these fasteners holds up great in this horrible environment.
