Could anyone tell me the ID of the transom water hose on a Bravo 1? I am going to upgrade from an Alpha 1 and I'm working out the details. I have closed cooling fed by 1 1/4" hose.
Thanks for the reply Vice Admiral Don and congratulations on your new rank . Yes I have researched it pretty well. I am picking up the parts as deals come along. My Alpha 1 seems to be holding up well to my SBC 400 repower, but I am extremely careful with my right hand. I am running a 14 1/4 X 20 prop at 5400rpm at wot but I know it will go faster with a bigger prop. Do you have the diameter of this hose handy?
I don't know right off hand what the dia. is, it really doesn't matter as it is a formed hose and fits inside a hole in the transom shield and the bellhousing. There is then an insert that screws into the hose to lock it into place. It is NOT like the Alpha setup.<br />The part number for the hose is 32-43437<br />You will also need a special tool to install the inserts.<br />Here is the section from the Bravo service manual on the transom shield. <br /> http://www.boatfix.com/merc/Servmanl/11/11a4r5x.pdf
