First sea trip in t38 honwave

[Martin]

I'd have thought it would stall in that scenario
But never say never

Hi tellum
A friend and I bought a t38 a few years ago and experienced the 'ripple' you talked about. We tried everything to try and get rid of it (including over inflating the floor) but nothing worked so we sold the boat in the end. I'd be interested to know if you get to the bottom of it. Sorry I can't be if any help!
Cheers

Thankyou all for the advice.. I will take it out on the river through the week and give it a blast. Probably my lack of experience and confidence in a sib in a choppy sea didn't help.will check floor pressure tonight with pump and manometer..will let you know any results.

A few things that could cause the issues you mention....
Trim wrong
Wheels Down
Faulty Bravo gauge
2nd man too far forward
wrong size or damaged prop

Closed vent on fuel tank???

It had been fine earlier in the day on the river so I would presume the vent was open

[Tellum]

Actually the river trip was on a different day ,sorry for the confusion. So I check the tank vent today and it was barely open,not screwed in tight but just lightly slackened off. I think I managed 2 or 3 full turns out,so could be the problem,fingers crossed have to wait to check it out. Pump all fine 0.8 on pump and manometer. Could the vent not being open fully starve the engine and not let me get full revs?.

[Paul B]

Yep if not open, you would be getting fuel starvation, and lack of power hence not getting onto plane

[Andy B]

Always check the simple stuff first

[Tellum]

Well just an update. Went out today hoping the fuel issue was the problem but no .and still the same on all trim levels. Went in the estuaries and had a play on all trim settings. It would be fine upto 7mph starting to lift looking good ,give it more and it nose dives like iam losing drive maybe ?. Full throttle 11mph with the front of the boat down . Back to the drawing board.

Have you checked the prop isn't slipping on it's hub

[Tellum]

Going to mark it and try it in a drum. Not sure if I can create enough torque to prove good or bad. Can they be repaired or is it just a case to buy new prop
