23cc w/ 200HPDI Performance?

[stoney]

Peter,
I believe the mileage number. Not because of the navman F3100, which is on it's second sender and due to be trashed because they won't replace the non working display, but because I travel 60 miles fishing and put in 20 gallons somtimes 15 gallons for the last 3 years. I believe my boat is a lighter 23SF than most I've seen. I removed the livewell in the back relpaced the transom with Coosa 26, have a 100 gallon tank, and I think the foam is dry. Sitting at the dock the corner of the transom is only in the water 1/2" and the splash well drains are 3" above the water. Sitting next to Scott's boat mine sits 3" higher. It also feels lighter than scott's when riding in it, but that might be because he drives fast and me and my herniated disc's like slow rides. I also have seen the hull thickness cores that other people cut out of the hull and mine is not that thick, maybe 5/16" thick at most. So I have a light weight 23SF but I love it with the 200 Yami. I just need more fishing time.

I can't read the HP number but I thought the old 23's were rated for 400. I still don't think a single 200 w/bracket would be "satisfying"

They are rated for up to 400 HP. The Savages are rated for up to 500 HP.

mine is a 89 23cc with a ttop i redone 3 years ago, rebuilt the transom with marine ply,recored the decks and cap with marine ply from the bottom side. But i still have the original 200 merc black max on it.it will top out at 41 by gps with a 19 prop. would love something less noisey and a little faster, but untill it shows me a rod i will stick with it.

I run a 25ft Bertram 1967 FBSF with a SINGLE 225hp Optimax swinging a labbed 15pitch Mirage plus. I fish with no less then 4 people and mostly full gear.

Ultra light with 1 person and 10 gallons of fuel, I just hit 40 mph on GPS.

With canvas up, 4 people, full fuel (80gallons), and gear, it will cruise at 24mph and top out at 36 mph.

This boat has a 10ft beam, and is over 25ft long with a flybridge. Planes off easily and stay on plane at 20mph.

Its all in the prop.

Just my 2 cents.

What are your RPM's a WOT? Are you running a 2:1 or 1.87 lower?
