  • Cape Horn 24 twin 150s porpoising, props, engine height, performance . . .
    "I recently picked up a 2005 CH24 twin F150's with Mirage Plus 17P which are 15 5inches Top speed is 45-46 at 5700 5800 RPM and the boat sure does like to porpoise without a good amount of engine trim and some tab The motors are mounted on the lowest possible hole I too read some posts on Propgods and was thinking about moving them up one hole
  • Cape Horn 24 twin 150s porpoising, props, engine height, performance . . .
    I can add some more info from our 100 mile run yesterday, in fairly calm conditions after the morning chop Running 31-33mph later when it was pretty calm, the boat still wanted to porpoise pretty good with zero tab and engines trimmed all the way in I had about 300lbs of ice and slurry in the front big fishbox
  • Boating and Fishing Forum - Permatrims on a World Cat? - The Hull Truth
    permatrim - 6 28 2004 5:09 PM Matt, Permatrims will stop the porpoising on your friends cat By having more lift in the stern and more trim control he will be able to stop the porpoising very easily
  • The Hull Truth - Boating and Fishing Forum
    with four strokes the formula seems to be a four blade prop, wedges and maybe a few lbs in the anchor locker They porpoise with too much weight in the back A good set of tabs are a must Great boats, I have an 89 215 with a 250efi Just be mindful of the wood
  • Contender 31 Mounting Height - The Hull Truth
    New 31 w 250 f strokes and wedges Has anyone tried to raise these engines to the top hole? reason I ask is that the wedges make the steering cylinders hit the transom when the motors are trimmed up, and the boat has a slight tendancy to porpoise when heavy On previous 25 we eliminated most of the porpoise by raising the engines
  • Boating and Fishing Forum - The Hull Truth
    Yeah I am willing to do all that , I want to tear into it and make it new again , my main concern is if I close in the transom And install an Armstrong bracket with twin 150 Suzuki’s or possibly 200s how will it ride And is it gonna ride too high in the bow , wanting advice from anyone that has done this with a 25 and how seaworthy is it , I want to replace the fuel tank, close the transom etc
  • Cape Horn 24 twin 150s porpoising, props, engine height, performance . . .
    I have a 23 contender with twin 200 hpdis When I got the boat it would porpoise badly I put bob's manual jack plates on and raised the motors way up Also switched from 21sws to 19 Rev 4s Lost a little top end but it rides like a whole different boat
  • Cape Horn 24 twin 150s porpoising, props, engine height, performance . . .
    Seems to me CH has to revise these hulls and provide a fix to their customers Not bashing cape horn i would say the same about contender who seems to have a porpoise issue to on the 23T models i think Ken knows his stuff as i fixed a porpoise issue on my rig and it was solely engine height I bumped the engines up and done My 2 cents
  • The Hull Truth - Boating and Fishing Forum - Pathfinder 2005 TRS
    It does want to porpoise slightly in flat water at a certain cruising speed, but one touch of the tabs fixes it perfectly The jack plate and tabs are super nice when flats fishing WOT 48-49 mph around 6100 rpm 4 adults can fish comfortably and there’s tons of storage space
  • The Hull Truth - Boating and Fishing Forum - Contender 23t
    The Bluewater 23T is a few inches wider, weighs more than the Contender 23T and does not porpoise
