So are you saying if nuts go outside the transom you can take off motor and move and not completely reseal everything? Seems risky. I believe mine now is bolted on nuts against the motor. I will be putting a motor plate on top bolts and checking the transom good while its off. I have never drilled in it and found wet though. Always good light dusty shavings on the bits!

That is a great idea, bolts on the inside...my motor could use to be moved up a hole, but I didnt want to mess with undoing and redoing the 5200. Bolts on the inside, no problemo.

The simplest things make my day sometimes.

5200 is tenacious stuff.... as long as the bolt is not allowed to turn in the hole the 5200 will hold up just fine... that said... a lil 'clean n reseal' on the outside of the transom wouldn't hurt a thing but you shouldn't have to pull the bolts out unless you let em turn... You'd pretty much have to WANT to mess it up.

Listen to Spareparts.
Have that HPDI serviced. Do the VST filter. Have the injectors pulled, cleaned and flow tested (they should be clean every 5th season).
One lean injector makes for a bad day.

Its on its way here now. Its going to my mechanics shop first thing. It has new injectors and filters but, he's going to run through it and check it out.

Long time member, "Pipe Dream" has been running a 200 HPDI since '03 or '04 on an '84 cuddy....look up his boat in the Gallery...some great boat porn there...

Where did you find your new motor...and do you mind telling how much you paid for it?
