23ft Seacraft with a single 175hp Suzuki

captbone · #1 09-11-2011, 02:03 PM

There is a guy on THT that just repowered his 23ft Seacraft with a single 175hp Four Stroke Suzuki (4 cylinder) and get 28mph cruise and 39mph top end.

Pretty nice numbers. Any one every have a 175 or even a 150hp on a 23ft Seacraft.

I think 175hp is too small. I doubt he truely gets those perf. numbers. I get those #s with a lighter 2-stroke 225hp.

I was thinking the same thing. If it's a CC then it will perform slightly better than a Sceptre, but those numbers do seem a bit high.

Wonder what rpms, prop? Seems a little fast, maybe that's including going with the tide or, wind or, running on fumes or, through a bottleneck. Or all the above.

Eggs . . . I had this same motor on my 18 . . . believe it or not the V200 on my 18 was only 44/45mph with just me onboard and 30 gallons of fuel using a mirage plus 17P. I'll put money that I can top 40mph when I put on the 15P mirage and shed one body in the 23.

Dog the do make different props,mine will almost do that with one motor trimmed out with way to much prop, (19p powertech 4blade) way to much for a single 150.

i dont even get those numbers with a 225

at 4400/4500rpm - I'm cruising at 28/29mph and topping out at 5800rpm 38/39mph. My gps doesn't lie (at least I don't think it does). That 175 zuke should perform better than . . . a 32 year old Merc v200 motor rated at the powerhead not prop.

I never would have believed it until this past weekend, but I now actually believe those numbers. I have been messing around with my pile of spare motors. Currently I have a 1979 V200 Mercury 2.4L powerhead on a 2001 200hp mid section/lower unit (This is equivalent to a mid 80's 2.4L 175). Propped right and the motor seems to have plenty of power to push the 23 . . . the numbers above are with a full tank 70 gallons, HUGE 400+lb pilot house, 2 adults, 25hp Kicker, tons of gear.
