Like many others before me the mid 90's jet boats powered by Chrysler's Finest the 90-115hp Mercury/Force Sportjet have become yard art with no other useful purpose.
After neglecting her for a couple of years and almost turning her bow into a tiki bar I've decided to turn her back into a super skinny water fishing machine.
Like many others before me the mid 90's jet boats powered by Chrysler's Finest the 90-115hp Mercury/Force Sportjet have become yard art with no other useful purpose.
After neglecting her for a couple of years and almost turning her bow into a tiki bar I've decided to turn her back into a super skinny water fishing machine.
My main motivation is that she floated in 4" of water with 2 + gear + motor + 10G Gas+ dog.
The plan is:
Pull the motor and housing
Fill the hole with 3/4" Starboard, heavy mesh and resin top and bottom in 2-4 heavy coats.
Reinforce Transom with Starboard, mesh and resin in 3-5 Heavy Coats, and a couple Stainless 1/4" L brackets tied to where powerhead previously lived. (Stringers)
Install Jackplate and new motor, then rigging
Gelcoat Transom, and create Storage / head / cabin in the old engine bay. (It's Huge)
The Questions:
Can I just fill the hole top side and leave the cavity below? (I'm thinking it will decrease my draft and is allot less work) {I've seen twin screws with a similar cavity just before the shafts, it's less pronounced and I'm sure engineered properly}
Will Mesh and Glass over/under 3/4" board to transom be strong enough for a 50-70hp, or should I look more towards a different direction?
POWER: The previous motor was a 90hp jet, I've seen 1 similar conversion with a custom transom outboard bracket and an 85 on it. I want light and like the rest of us as fast as reliably possible.

Fill the hole with 3/4" Starboard glued in from bottom, heavy mesh and resin top and bottom in 2-4 heavy coats.

Will Mesh and Glass over/under 3/4" board to inside transom be strong enough for a 50-70hp, or should I look more towards a different direction?
POWER: Rated for a 90jet I want light and reliable so I'm thinking 50hp Carborated Yamaha or 07+ Yamaha fourstroke 70+
