Verado on Seacraft 20 Super Fisherman?

[TPG]

Has there been any documentation done on how far to move and what to move depending on weight of motor?

Some days I long for the "ClassicCheckmate" site.

Check out this thread, posts no. 15 & 16. Based on the successful experience both Connor Davis and I have had with cramming the Seafari's large cabin full of gear and dive tanks, I believe it's very difficult to get too much weight forward in the 20' hull! It seems to have plenty of lift and buoyancy up front. I've run with 4 dive tanks plus a bunch of gear in the cabin, resulting in a great ride in very rough seas and Connor has run with 6 tanks in the cabin with similar results. I also concur with Connor on power . . . my "150" E-TEC (actually 165 hp at the prop) has so much mid-range torque that I've never used more than 50% throttle when getting on plane, and I typically cruise at about 25 kts/3700-3800 rpm and about 35% throttle. I hardly ever use all the power available.

If you stay with a ~400 lb motor, keep the casting deck, and move the console, batteries and gas tank as far forward as possible, I think you'd have good results. You might ask No Bones how far he moved his console, as his rig seems to be well balanced. If you add a bracket, you'll also want to add some large trim tabs, a 4B stern lifting prop, and maybe a fin on the AV plate.

So, it was `82 when the transom went to 25" and the scuppers out back?
Always wondered when SCI did those mods.

Did they raise the deck again?

As far as moving the console forward...
The distance from the console seat to the casting platform is close
to a size 13 shoe.

I am now 10 1/2 so I moved it 1 1/2" forward to allow for others to put
their feet down without quacking.

Sandy, all I know is that the SeaCraft Industries catalog is dated 1982, and I also have a March 1982 article from Trailer Boats magazine by a writer that toured the new plant in Tampa. It was obviously written at least a couple months earlier, and said that "the new models were to be unveiled at the Miami Boat Show, which is always in mid February, so the longer models evidently began production early in 1982. They probably built new molds to increase the length to 20'4", so my guess is that the 25" transom was incorporated at the same time. Potter had already raised the deck once but maybe they raised it again when they raised the transom. Do you get wet feet with your 375 lb motor if you leave the plugs out?! Denny

Nope, no bracket. Everything I've read and seen says no bracket, just raise the transom and keep the motor light.
