Begin Glasswork

The boatbuilder opted to use the existing base knowing that it was very stable, level and centered. We wanted to raise the mount pad 2" to 2-1/4" to get the prop location we needed. They began fabrication of a round plate that is going to bolt down to the existing mount ring. Bolts are going to be countersunk and glassed in. 5200 adhesive will be used to ensure a watertight seal with the existing mount ring.

An additional rectangular plate with studs projecting upwards will be fabricated. The studs will be recessed and glassed in, then the plates will be adhered together with 5200 adhesive. Fiberglass mat and resin will be used around the base to fill in the gaps between the new and existing fiberglass. The rectangular base of the motor will then slide onto the studs and hard mounted to the new fiberglass.

8 holes around the round plate will secure it to the original motor base. 4 holes around center cut out will have studs that continue through rectangular plate. There will be an additional 4 studs going through the rectangular plate only.



 

Motor w/rectangular plate 

Both plates—rectangular plate has a rectangular cutout to accommodate rectangular relief on the bottom of the outdrive base. Circular plate has an oval shape to maximize amount of material and stability.
