Completed the survey and sea trial today on 2001 340 Dancer with 454/310 HP motors and 3 blade props. We have made a deal on the boat and will be ready to close next week just as soon as the owner makes a couple of repairs. One of the repairs is to make the trim tabs operable. With just under ВЅ fuel ВЅ water and 4 on board the boat did get on plane with the tabs up. 4250 was max RPM. But it wanted to fall off at 3400 RPM. Does the 340 need tab to stay on top at 3400 RPM cruise power? The top speed we saw was 28.2 Knots GPS. Is this a speed that would be expected at 4250 RPM? We are excited about the boat. It has the Cherry interior, which is very nice.
 
RPM's are about right. Might get a little better if it had a clean bottom. 3400/3300 RPM's on 340's is norm to keep them on plane.
 
Congratulations! I'd have to agree that the numbers are all about right. With a lighter load I can plane at around 3200 but that's about it. I generally cruise with tabs on, as they do fall off plane at the lower rpm's.
 
Thanks Sko and Skippy. We are excited about the boat. This will be our largest powerboat and our first twin engine V- drive boat. We are moving up from a 270 Dancer with a single 454 and B 111 Drive. So we have much to learn about this boat. We plan to drive it home. It is 650-mile trip. It will get an annual maintenance before we depart. We will carry some spare parts such as belts and fuel filters and an impeller. At 3400 RPM what speed can we expect and what fuel burn. I am planning on .85 MPG.
 
vriceflyer,

Keep us posted on how you like the boar after the trip. I'm looking to move up also to a 340 from a 300 (whenever I can get the 300 sold!)and I'd like to get your impressions of the 340.

Thanks and enjoy
 
Remsberg,

I have run a late model 300 and owned a 270. They are sports cars compared to the 340 (in my very brief experience with a 340). That being said we are looking forward to the 340. The interior room, the larger cockpit area and the solid feel of a heavier boat. By the time we get it home we will have spent 4 to 5 days on it and run the engines about 32 hours. I should have some opinions then. I am betting we are going to love the boat.
 
I had a 260, and have driven a dockmates 300 with 6.2's and BIII's - the 340 is a different feeling - mainly due to size - less sporty feeling.
 
If the 340 is like the 330, you will need tabs to stay on plane at cruise. My 6.2's cruise at 3800 and if I raise the tabs completely, she squats terribly. Mrs. Robinson has the same boat w/ 7.4's and has the same problem exacerbated by the additional weight. Four blade props will help some. If SeaRay was still using the 22x9 tab, have an entension welded to make into a 22x14. That will made all the difference in the world. I talked to Bennett. The 22x9's were all Sea Ray was willing to pay for. According to Bennett, the extra tab will not put undue stress on the system. I am having it done when I haul.

I tested a "new" 2007 340 a few weeks ago with 8.1's and v-drives and was amazed at how quickly it got out of the hole and on plane. Far quicker than my 300 with twin 5.0's. As for cruising and tabs I really didn't get a chance to play there.
 
My 340 was repowered by the PO and went to 454/340 hp, and deliberately overpropped. With My set up getting up is tough if the whole crew is sittin on the transom bench,but, if they come forward to the helm seats she comes right up, and I use tabs to get up.

Because she is overpropped, she will stay up at 2800 without tabs,and 2400 with them.

Overpropping costs top end but you pick up the savings in the midrange.
