Jet Pumps / Ride plate and shoe
« on: January 20, 2011, 12:28:24 PM »
I'd like to install a ride plate and shoe on my 18' Tahiti , I'm running a Berk pump with a split "B" bowl and it's not a set back if that helps also a droop and place diverter. I've looked at several vendors and have seen some "adapt a plate" offerings that state you don't have to remove the intake from the boat to install the shoe and plate.

Any pro's / con's to this or should I just plan to remove the intake and machine (not sure) what machining is required to mount the shoe.
Don't mind the work...just want to do it correctly the first time. If machining is mandatory what exactly is required ~ is the shoe recessed into the intake and thru bolted or is this just a mill a flat and drill and tap deal?

Really appreciate your input.

Engine Mechanical / Electrical / BBF Cam Specs

Been long time reader but new to the site, I picked up a 76 Tahiti super tiger last year, the previous owner said it would run over 80 @ 6K on GPS.
I've taken it out a few times and have blown both bowl and nozzle gaskets out and have reversion problems with water in the exhaust when I try to run water thru the headers. (it runs great dry but cooks the sides of the boat and melted the carpet!)

The engine is a 514 (4.44 bore with 4.14 stroke) 10.5:1 compression with large valve 2.25 / 1.97 bowl blended & ported Dove "C" heads. the cam is a Erson JB300 but I don't know what the spec's.

I'm guessing it has a "B" impeller but will find out when I pull the pump apart.

Anybody have spec's for the cam and will the water restrictors that mount in the header -8 line help me with the reversion problem. I'm hoping to just allow enough water to get a LITTLE steam thru the headers until I can set it up with Lightning or other double wall versions. Look forward to your insight and help.
