Specific info needed on 20' Sceptre hull
 

Considering picking up an older hull for a resto and am looking for some input on a 20' Sceptre hull, hoping some owners can fill me in.

What is the freeboard/gunnel height on these boats in the stern corners and then closer up by the helm?

Is repowering these hulls an issue considering the weight of a new 4-stroke in the 115hp-150hp range?

Lastly, does anyone have firsthand knowledge of this hull and a late 80's early 90's Grady 19 dual console that can offer a comparison between the two?

50 views and nuttin?

Surely someone out there has repowered a 20 sceptre with a small 4-stroke that can add some input??

Thanks guys

I think it was your asking for the comparison to the grady that limited your chance of any answer.

The 20 Sceptre was a pretty rare bird so there may not be any 4 strokes on that boat . I have seen new 150 etecs on them, and i/o.



You might want to PM Strick and see what he is putting on his bracket Sceptre.

I have a Sceptre 20' with a 2002 Yamaha F100 four stroke.The boat is currently on its mooring but as soon as I get down to it I can get the info for you.It does not ride stern heavy at all,any water that does get aboard goes foward on it.

Freeboard at stern is 23" ...
Re-powering is a concern. Weight is the enemy of maximum performance. They only have a 7.5' beam and a sharp entry so buoyancy is not like some clumsier boats. The 20 is strong and nimble . Recent model re-powers I'd consider:

DI 2 strokes
90 (330 Lbs)and 115-130 Etecs (375-390 lbs)
115 Optimax (375-390 lbs)
115 Tohatsu (375-390 lbs)

4 strokes
90 - 140 Suzuki (345 - 421 lbs) the 140 Zuke is the biggest I'd go only due to its power to weight advantage.
Merc 115 lbs (400lbs)
Yamaha F115(400 lbs)

The lightest 150 hp 4 strokes are the new Mercs at 455lbs and that is simply 100 lbs to much.

Second hand, the Sceptre will ride much better than the Grady 19 DC - no comparison...:cool:

Ditto Terry.....;)

That's a good list Gillie. If one was going to consider the 140 Zuke at 421 lbs, you might want to also consider the 150-175-200 E-Tec, as they're only about another 10 lbs heavier. If you include the weight of 6 qts of oil for the 4 stroke, the difference is even less.

I can get some measurements for you. I am considering a 140 suzuki for mine but I am adding a very large flotation bracket on the back of the boat. I cant give you any info on the ride because I have never been in one but I am confident I will like it. :)

Good point, Denny.
I know those numbers are all dry weights and I didn't even consider the extra 10 lbs of oil:eek:

I was going to throw in the Etec 6 cyls but thought even the 140 was pushing it... But hey, csicknick has a 140 on his Seafari and drags 300 lb bft over the gunwale like "whats the big deal?" so I as I rethink this, a 25" transom goes a long way to maybe allowing more weight.... Nick's still sticking fish, right?

Drop us a line Nick, how'd the striper derby go???

I've been on Ebeach's restored Sceptre a couple times and he powered it with a 130hp Yamaha 2S. To me that engine is perfect on the the 20's in general. I don't believe Yamaha makes that engine any longer so you'd have to go used or stumble onto a leftover.

Thanks guys for the input. Was looking to purchase the 20 sceptre that was listed here with the etec 150 on it as we were very close to the seller but turned out we had just missed it.

The boat is for my Father, and we're still looking.

Ideally I'd like to find a little 2s 130 Yamaha as I had run the 115 for many years on a different boat and was very familiar and happy with it.

What is the correct shaft length for these hulls?

Original transom = 20"
