I just purchased an 1987 29 Aquasport Tournament Master with twin yanmar 240hp diesels. In the short sea trial I noted it was slow to come up out of the hole but did well once up on plane and the turbos kicked in. I also note it tends to be bow high and wondered if that can be brought down to reasonable level with trim tabs. Any one has experience with this model I would appreciate talking with you. Thanks, Fighterpilot
The problem you're faced with is not unique to Aquasports. It sounds
like one or both of your propellers have too much pitch and are
lugging. One test is to open up the engines to see if they reach the
rpms recommended by Yanmar. It should be within 5 - 10%. If not,
you should have them "tuned" this winter. They could also be fouled.
Bob, thanks for the reply. Regarding the bow high/ slow out of the hole, I did find I had at least 1 inch too much pitch on the props. My yanmar diesel dealer has repowered an aquasport like mine and said it is typical to come up slow until turbos kick in. I could reduce more pitch and get a better hole shot but than give up some more knots. As to the sound, I put some undercarpet insulation on top of the deck over the engines, hatches, etc. and then some carpet on top of that. All the difference in the world. Again, thanks, if you know where there is a souce of literature, like owners manual, wiring diagram etc. I would like to aquire same. Fighterpilot
