Angier,

I own a 1990 Sea ray 29' boat. It has twin 4.3 IO motors both with the= same pumps that are in our airplanes( except the way they are set up= ). On these pumps are smaller looking compact relays, lately I = have decided that if I needed to replace mine I would look into theses as t= hey are still working after 23 years in a very bad environment and sal= t water. It might be worth looking into. They are Merc Cruisers. Don't= know about continuous duty but in a bigger boat you are always adjus= ting the out drives up and down depending on the conditions and power. They= must be designed for wet environment. I bet they are not cheap Chinese uni= ts.

About =
3 mos ago, the high side relay failed while 4ZQ was up on jacks. I figured=
=20
that old age (original kit) plus X number of cycles during construction too=
k=20
that relay to the end of its useful life. So trying to kill two birds with =
one=20
stone, I replaced both hi/lo relays with new (chinese) from the local auto =
parts=20
store.

The cause of yesterday's gear failure turned out to be the NEW low side rel=
ay,=20
and it had just 14 cycles....

So, on the assumption that relay quality differs, who makes a HIGH quality =
relay=20
with the same footprint as those that
came with the kit? Any reason why they should not be continuous duty type?
