That area, the heads pretty thick.
You should be able to re tap the holes easily.
I've seen the cover held on with 2 screws and sillycone.

Hey Jerry what grade hardware shoud I use for the t stat houseing?

also ran the engine on the stand. Pritty much burned threw 1 gal of gas in under 30min. Was at a fast idle still seems excessive to me. Anything I can check?

 

[jerryjerry05]

Those bolts aren't tuorqed too much and almost any stainless screw will work.
Don't use anti-seize but do use grease when reinstalling.
Don't use a slotted screw.

Hey Jerry does the fuel burn I reported sound normal

 

[SkiDad]

it sounds normal. I would burn that idling around and about 8-9 gallons per hour skiing at 4000-4500 rpm

Couldn't find the usage you mentioned?

My 88/85's 2.3 miles per gal.
In all the years I maybe ran my motors wide open 3-4 times.

Just make sure the props the right one and don't load the boat too much.
I wanted more speed and changed from a 17p to a 19p
I got 3 mph. and the fuel usage went up 15-20% more!!
Now usage will vary depending on the way it's used.
