Title: Does Anyone Know Who makes this engine mount?
Post by: maddogg20 on January 14, 2009, 04:18:11 PM

Heres a pic of the rear motor mount from my friends 73 kona. It has a BBF in it and I have never seen this type of rear engine mount before. it has the 2 feet that stick out and go right over the 2 front mounting holes for the jet and theres a 1/2 inch bolt that goes thru the mount, thru the jet and thru the bottom of the boat and it has washers and a nut under the boat. Any Ideas? it looks VERY strong and my friends BBF pushes upwards of 800HP and it hasnt given him any probs.

I dunno who made that. But if you think about it, the engine weight and torque would be better on the stringers(like a 4 point or a rail type set up). JMO

That motor mount setup is  very typical Jacuzzi rear installation , that is the Jacuzzi equivalant of what we call a "three point mount". (auto type side mts and the rear support)  Berkeley set ups use an rubber insulator that has a bell hsg clamp over a jet drive brg cap , we typically reserve (recommend ) "three point mts" for low to moderate HP up to 400 or so ... Tom

Big HP should have 4 point mts minimum and rail system as Omar displayed is the weapon of choice IMO !

more Rail mt pics
