Bolts

Remounting plate, engine. 9/16 or 5/8 bolts?

[Strokerdean]

On my prev Stroker I used 5/8 grade bolts and nuts. On my current Stroker I used 9/16 grade 8 bolts and nuts. I haven't experienced and stretch with either.

9/16 grade 8 on mine.

NO stainless.... grade 8 make sure it has the angle or channel on the inside for the bolt backing plates

9/16 fine thread, Fastenal grade 9 Ecoguard coating

Ok, do happen to have length needed? Using same style channel that is in boat except stainless steel.

I think they are 4" bolts but it's been a long time since I measured them. Some one else should chime in that is more familiar with what they use like CB marine, Kurt, Wayne, Paul and I'm sure others. If I can find a stock bolt I will measure it.

Thanks

For my particular setup, this is what I used. I strongly encourage you to measure your setup before buying / ordering. Too many variables for a 1 size fits all approach

Motor and Jackplate bolts:
Motor>static jackplate top = 3"
Motor>static jackplate bottom =2.5"
Top static>hydro jackplate = 2.5"
Bottom static>hydro jackplate = 2"
Transom>hydro jackplate = 4"
1.5" flat washers =
1.17" flat washers =
All bolts, nuts and washers Fastenal grade 9 ecoguard coating, torque = 130' pounds

[DewRonInc]

Sure the length will be close, especially on plate to engine

[DewRonInc]

I am using 3 inch stainless channel 5 inches long myself

When redrilling do your boat a favor remove the jackplate don't just try to redrill move it out of the way so you can get the holes right and use marine silicone to seal

Dont worry all off now

Those are mighty big bolts, unless you're saying socket size instead of the bolt size. Just sayin'

With the amount of setback and HP that some run on these boats these sizes are spot on.

[DewRonInc]

Mine is 15.5 setback with a 300xs hanging off back.....

[Strokerdean]

This would be the dia. of the bolt.
