I'll tell you how it works in a few month's

It would be great to know how this system works out. I have heard so many opinions on this topic it is making my head spin.

what size are the connections on that???

Offshor was one of the first to use one. He has pics of it installed on his motor. Here is his post on the same subject. I have been using the same idea for 3 years now, but that was before I new about this one. this makes it much easier.Merc P.Relief post

would it be better if it opened at 17- 20p.s.i

The 2 pieces with the bolts thru it look like the poppet valve assm. off a merc v-6 outboard and probably is.

Does anyone know the connection sizes on this part?
