I am looking at much bigger set up, like the ones he has on the cat.
He said he would like the cash right now.
There is no "try before you buy" with ATB engines.
This is not Wal Mart or Chadwick homes.
By the way, the toilet is not working in the Walden house.
Can you get that looked at.

I was wrong on the fiberglass thing....
To fill you guys in a little more.
When you build a boat, regardless of how straight the mold is the hull shrinks as it cures. This is one of the reasons they release from the mold.
The biggest issue is heat, good shops can control the exotherm in the resin, but most cannot control the humidity or air temp, a hot boat will shrink more. Generally winter built boats are better.
As for the shrinkage, all the straight hard lines on the hull do a better job of retaining there design shape better than large flat surfaces. So the edges for the transom, chines and strakes typically hold, and the big flat areas between them shrink causing a concave area. This is most noticed in front of the transom as this is the most ridged part of the hull...... and hence the hook. A good shop will grind off the gel and fill the hook with structural filler then regel the hull...... and real good guys will leave the finish in 400 grit, with the sanding lines following the direction of water flow......... this last bit is only ok for boats that are kept on lifts or are trailer queens. As gel is like your skin and will absorb anything....meaning it will stain.
Lastly... NEVER and I repeat NEVER wax your bottom.
