Official 330 Sundancer Thread

[Creekwood]

I have the same boat yr and all- I have 17 x 17 3 blade props- tops out at 43 mph- and loves to run at 3200 rpm @ 28.5 and if conditions are right its approx. 29.5 MPH

Your signature says you have a 300. I have a 330. Not sure of the weight difference, but that would account for the different props with the same engine. My 330 with 3 blades 16X16 runs right around 30mph at 3400rpm

Anybody know the tube size for the prop shaft? I’m ordering seals this weekend.

Thanks for the quick response. We’re a family of 5 and I didn’t know if that could have some effect getting on plane with the extra weight (when another family decided to join us). Sounds like it’ll be just fine. Deposit has been put down and our survey is in April, looking forward to a summer on the lake.

Little late to the game, but first welcome to the family! Second, I also have a ‘98 with 310s. Runs great with family and friends aboard!

Are you sure it was only at 2K and it wasn't the tach being off? What did the synch needle show? If starboard engine was at 3k and the other at 2k you would not be on plane and the boat would be turning hard to port. Was that what was happening?

 

[Wave Rider]

Agree your tach may not be working. Try tapping or flicking it with your finger to see if it moves?

We recently got our 330DA back to running condition and took her out for a test drive. We were able to idle through the canals to the open water of Tampa Bay where I pushed the throttles ever so gently to 2k rpm and all was fine. When I went to push a bit faster I saw that the starboard engine reached 3k but the port was still only at 2k. With the transmissions in neutral, both engines rev up past 3k without issue leaving me to believe this is a transmission issue.

Any simple items to check first before I call a $90/hr mechanic?

I had a similar issue recently. I’m used to boating in Missouri versus in Florida. I hadn’t had the bottoms cleaned in far too long. Had a diver out. After two hours of scraping, it ran like a champ!

My '99 has 1.5" prop shafts.

thanks, I confirmed my shafts are 1.25 from my prop repair place. Looking for the stern tube size?

By "stern tube size" are you referring to the brass strut just ahead of the prop? If so, you would want one that accommodates 1.25" shafts.

Sorry, no, I, taking about the tube the shaft passes through the hull. I believe it’s 2 1/2” but checking to see before I order. I’ve read through this whole thread. Tons of great info.

That would be called a shaft log and dripless shaft seals are usually part of the program. May I humbly suggest you consult with a marine mechanic before purchasing anything.

Thanks for the terminology clarification. I appreciate your suggestion. I understand they are dripless seals and it’s likely I have Tides seals. Planning on switching to a carbon flange PSS setup. Unsure I’ll have the time so I may have the marina do the work but was hoping to get the seals ordered.

Replacing the Dripless Shaft Seals on a 330 Sundancer with V Drives is no easy task… Are they currently leaking?

First, you will have to pull the props and shafts, then… I don’t know what you would have to do to gain access to the Shaft Seals. Maybe pull off an exhaust Manifold? Move the Hot Water Tank? Remove the Engines!?

Please let us know how you will proceed?

hey hows it going,
i have a 95 330 da. My shafts are 1.25 and my stern tubes are 2 5/8

You can call Sea Ray with your HID and they can tell you your size

I need a Home project. I want to make a table for the cockpit but our marina is closed and boat still shrinkwrapped. Can someone with a 97 or 96/98 330da please measure the Cockpit table dimensions?

I’ve read this whole thread and some have mentioned they did it without removing the engines. I know it will not be fun. I do think the exhaust manifolds will need to come off. I have some gen work to do anyway so that will help access there too.

Shaft seals are leaking hence the replacement.
