Post 1648 w/ 23hp SD
MM Brand: Home Built
Horsepower: 23
Boat Brand: Fisher Marine
Boat Size: 1648
Boat Layout: 5' front deck, two seats in boat, rear interior pods with seat receivers on top.

Speeds | Shallow Water: N/A at this time...lake is too high
Speeds | Deep Water: 22mph GPS
Total Boat Load With Gear Etc: Me 175, 12 gals of gas, light fishing gear, battery, anchor and misc marine gear
Conditions Tested In: Slight chop w/ about 5mph breeze.

Comments: With my first belt setup, 1.5:1 ratio, I was only getting 18mph. I change to a bigger top pulley, 1.2:1 ratio, and picked up 4mph. I am adding a cam this week, so hopefully it will pick up alittle more.







This video was with the 1.5:1 pulley ratio.

Added a cam to the engine over the weekend. I went back with a governed cam from Performance V-Twins and picked up just over over 1mph. I am only turning the engine alittle over 3800 right now but plan to adjust the gov. up for the next outing. Al, at Performance V-Twins, said the cam should continue to make power until 5500 but I'm going to stay around 4100 - 4300 in the water. With me (175) and 6 gals of gas it GPS's 23mph deep water. The lake is still too high to get any shallow water speeds.

Went out yesterday with my wife, daughter, small cooler, 6gals of gas, two batteries and all necessary safety gear + some. GPS hovered around 21.7mph and bumped 22mph a few times in deep water. I was pretty happy :mrgreen:

great post. Looks like you did your homework on the rig. Looks good. Pm me some plans on the motor. I would like to try and build one for my little boat. What did the motor end up weighing?

Nice mine. Is your boat riveted or welded?

Some new pics....I painted the cowling black...the red was too harsh.



New clutch cover and started the camo process.

Cowling is high heat gloss black from Advance Auto. Camo is rattle can from the HD. I will be using the tan for the stencils.

Did you just scuff up with a Scotch brite pad or something? Looks good

Thank
On the cowling I didn't scuff it at all. I cleaned it real good with acetone and sprayed over it.

On the frame, I power sanded with 120grit, cleaned with acetone, sprayed with self etching primer, then with camo paint.
