I am not disagreeing. I used to have a different Riviera Cruiser with the
same problem. Not sure I can change the mounting height, but I think I can
add a water deflector to keep salt spray away from the powerhead lower
cowling. I will be sure not to affect the airflow, just water.

Earth to Mike................. If water is entering the center of
your engine cowl, adding a water deflector (whatever the hell *that*
is), is a lot like rearranging deck chairs on the Titanic.

1) I can't imagine a situation where the mounting height *can't * be
adjusted and,

2) You *really* need somebody, that knows what they are doing, to look
at your boat.

I am using this as a guide for mounting height.

will measure where my mounting bracket is on the transom tomorrow at first
light.

Here is a typical transom engine mounting for a pontoon boat. I added the
red arrows to show where salt spray typically enters the powerhead cowling
at the gasket. I will add a small length of aluminum or rubber flaps to the
transom to limit the salt spray. see:

On my harris there are 2 deflectors on each side of the motor bracket
about 4-5" wide with about an inch of the outside edges bent down
around 30 degrees to channel the water aft. One is near the top and
the other about half way up the side. You could get an aluminum
fabricator to make up something for you, maybe shaped like a square C
crossection that would bolt to what you have. Use aluminum bolts (Ace
Hardware has them). Stainless will eat up the aluminum and steel will
rust.
---------------------------
Success. Here is my first test and afterwards there wasn't a single drop of
water on the cowling. http://www.youtube.com/watch?v=SrMiNfpOLqQ

ps: What did you mean by "Stainless will eat up the aluminum... "

Stainless will set up electrolysis in the aluminum and you will end up
with a big white powdery hole where the bolt was.
Salt water will really speed up this reaction but any water will do.
There is a teflon compound you can put in the joint to slow it down
but if strength is not a real big deal, aluminum bolts are better.

I am very glad you mentioned this concept. I understand what electrolysis
is, but never delved into or really thought about what metals are
sacrificial to the other aside from my anodes. I can find aluminum, but how
about just plain galvanized screws/bolts?

In sal****er you will get better results using stainless hardware
bedded in silicone sealer.

If you are a lake boater you can get few years out of hot dipped
galvanized but bear in mind you are doing this because they are always
wet. In salt water you won't get a season out of them.
I can take some pictures of some stainless inflicted holes in
aluminum. They put stainless snaps in the rail on my boat and they
just fell out leaving a hole your thumb will fit in.

It may depend on the type of aluminum. Some alloys are more corrosion
resistant then others. Sailboats typically have aluminum masts and
booms with stainless hardware attached with stainless fasteners.
There are corrosion issues if the fasteners are not bedded properly
with silicone or never seize, but the usual failure mode is that the
fastener becomes corroded in place and can't be removed without
breaking it.
