As you can see mine needs ALOT of work. Had to rip out all of the rot first and then a bit more for safety. Filled with two sheets of marine plywood and secured with ARJAY/ cloth and resin. Tomorrow (weather permitting) im going to finish glassing the transom and then
i will move on to the bulkhead(wall behind back seats) and then finally the stringer. I am anxious to see how your boat performs with the Verados. Please let us know once you have had a chance to run her .

Looking good! Getting started is half the battle!
Did first sea trial few days ago. Super smooth. All all systems working well except for a bad connection on the starboard trim actuator. Easy fix but made trimming nearly lol
72 mph at 4950 rpm. Neutral trim. 28 bravos spinning in. 6% slip. Propshafts were nearly 3 inches UNDER the bottom. 100 gallons of fuel. 600 lb load. Starts porpoise at about 65...seemed like it tarted to settle at about 72 ...that's as far as I pushed it.
Propshafts been raised 3.5 inches now at .5 inches Above the bottom. This should make a drastic difference in performance and handling. Possible up to 10 mph according to comparison. But will see what happens next time out . Also not sure the bravos are my best option...going to try some hydtomotives and some outboard over hub choppers and cleavers .

First sea trial
WOW!!!!!!!
For 1st time out those are amazing results, based on those numbers i don't see why you wouldn't hit 85 mph !!! With my verados i know they rev til at least 6200 so you have at least 1000 RPM left on the engines. Also
you need to be able to play with the trim, i can tell you on my other boat (i know V bottom is a different animal ) 313 Chris Craft Stinger Twin Verado 300 outboards, it LOVES trim. The engine height is crucial as well, i got lucky on my
313 that height was perfect first time out. That boat does 69-70 mph with a T-Top, 150 gallons of fuel, 4 people. I have a feeling that once you sort it out, she is
gonna be at least 10 -15 mph faster. Thanks for your post, gives me great hopes !!!!!

Thread back from the dead lol
so testing after raising the engines yielded virtually no improvement to speak of other than handling. (Much better I all aspects) and a slight blowout while tipping over onto plabe. But...i figured out that my engines are only 275hp. So I've just got too much prop for them as they are. The 28 bravo io props will be an ok all around prop once i send ecms off this spring and do 345 tune from Whipple. Should get the boat to 85-90 mph without much problem. I've got some 30p cleavers and 28 lightning ets and some 29p mirage plus props to play with also.
