New bottom paint and servicing

Update to engine height, I lowered the engines to the factory recommended height (all the way down) with no holes left. I haven't seen much of an impact in the performance fuel economy wise, still running 4,350rpm getting 32.5-33 mph and around 25gph. Around 100 hours on them now. I noticed an...

Top speed is about 48 MPH. I'm gonna drop them down at least 2 holes. The boat feels great with the 350s, I just can't trim using the motors...

So far so good. They don't weigh much more than the 300's, so just a torque issue. I know Grady will say it isn't rated for that much power, but seems fine so far. My Grady wasn't engineered for the 300s either lol.

Good day everyone! I recently repowered my 2003 Grady Express 33 from a pair of DF300s to the new Suzuki 350 duoprop and the performance is great so far. I run them around 4,300 - 4,350 RPM at about 34 MPH burning around 26 GPH (1.3 MPG). A question I have is the boatyard put the engines on near...

There was a bad breaker in the breaker panel leaking current to the neutral. Replaced the breaker and all is good again!

My boat DOES have a galvanic isolator, I am suspicious of it as well...

My electrician verified that the shore power and cable are good to go. Something on the boat...

2002 Grady White Express 33 reverse polarity Has anyone had any experience with the reverse polarity light coming on the AC panel? I have tried several different shore power locations and tried different shore power cables. I removed and inspected the shore power inlet on the boat for obvious...

Update on my craft - the owner from 2005 repowered this boat with DF250s (new) but for whatever reason put long shafts on. The engines are pretty low in the water. I have a couple jack plates on order to raise them up about 5". When running the cavitation plate is way under water. The techs seem...

Its a 28' boat with 3 blade 16x18 props I am hunting around for some loaner props to try out something else

Ok I got a full tuneup, that helped, new plugs fuel filters etc. The WOT is now 5,200 and at 4200 rpm I am running about 24KT. The motors sound better at 4200 then at 4100. The props are stainless 16x18. I am thinking I have the wrong props. Sounds like the spec on the boat is a 15.25x19. I ran...

I am a new Grady owner and I so far love this boat. I am experiencing some sluggishness however that maybe someone has seen before. The engines are 2005 Suzukis with around 450 hours. Not sure as to the prop pitch, but checking today. At 4,100 RPM this boat is planing, but only cruising at...
