Imco Powerflows
 

JUST wondering if anyone can tell me why my powerflows
don't have jumper hoses from the manifold to the risers, and
every other set I see does? new to the outdrive stuff, used
to over transom bassett's , if ya know what I mean!

older set maybe open manifould water flows though manifould into risers trough a gasget like water flows throught engine block to the heads paul from england

THATS what I was thinking, but their factory on a 98 boat, and
the others i've seen on older boats with the jumpers

Imco's have a wet joint between the manifold and the riser instead of using a jumper hose.
If there is a hose hooked to the riser bunge, then it is from the bypass on the older 4 hose tstat housings.
Click the link and on the picture and you can see where the water flows through on the gasket.
