my silent choice is leaking water out the shaft do they make a seal kit for them and were can i get them. Are they a pain to do and any helpful tips.

If it is the factory merc style they pretty simple to do. I just did mine and the parts are kinda pricy from merc but I think I saw on here somewhere about getting seals and bushings from another supplier.

As far as the repair goes I drained my manifold and riser before I took the riser and diverter off, once you have the diverter on the bench make note of its assembled state. Then remove internal flapper and the rod. The seals and bushings are probably pretty stuck so get a good seal puller to assist you. Once that stuff is out clean it up good, reassemble and reinstall in boat

If they are CMI, all you will probably need are the shaft seals -Carquest pn 471442.

my lightnings leak as well...

How do you tell which ones you have, i have gill manifolds my silent choice or polished stainless that came on the boat from fountain i have 500 hp carbs.

I just bought the parts to replace the bushings/seals and one busted butterfly in my Imco Sound Advantage.

What's the easiest way to get the diverters off the engine? Marine exhaust hose is sooooooooo stiff and a bear to work with.

Just pull a seal out and take it to your local bearing/seal shop.

Just need ID and OD. Nuttin special. I replaced my seals yrs ago when I rebuilt mine.
