URGENT 350 Mariner Transmission Vibration
I am new to the forum, but excited to see if anyone can help me.
I just bought a 2000 350 Mariner and after one week I found a really bad vibration coming from the port side while underway over 2500 RPM. Anything below 2500 RPM is smooth as silk. I brought her to the ship yard to be hauled out for a quick check of the props and drive lines. After inspection, the props are good, drive lines are straight, cutlass bearings good, but found play in the port side gear when turning the props. The mechanic at the shipyard says that the gear needs to be pulled and looked at (Rebuilt/Replaced). I have a couple questions below I am looking for advice/answers on.
1- Does the motor need to be pulled in this model Carver to get the tranny out?
2- I cannot find the data plate anywhere on the transmission to get model/serial#. What is a good number to call Carver direct to find this information out??
3 - What is a typical cost for a job like this, rebuilt or replace transmission?
Thank you all so much for taking the time to read this and help me out.

Re: HELP 2000 Carver 350 Mariner Transmission Vibration
First, yes the motor has to be pulled to pull the transmission. If your boat has gas motors the transmissions should be Velvet Drive 71c V drives, the data plate is going to be on the right side looking forward.
As far as contacting carver, if you go on their web site and click contact, fill the form out and they are really good about getting back a hold of you same day.

Unless they've ruled out the above by doing proper checks, I wouldn't even consider the tranny. While a tranny issue is a possibility, it really sounds like a running gear or alignment issue IMO so I'd be going there first.

Re: HELP 2000 Carver 350 Mariner Transmission Vibration
I am having the engine alignment looked at this weekend along with a full inspection of plugs and firing.
I also have a hard time believing it is the tranny. It runs smooth up to 2500 RPM and then after that there is a vibration, then cannot get up on plane smoothly. The vibration consists all the way through throttle unless I back it down below 2500 RPM. It will also have the vibration from a quick power up to blast up on plane. It seems like a drive line issue, but when we had it hauled out the shafts were straight and the props were fine. I am hoping to learn more this weekend and maybe it is as simple as alignment or the engine is misfiring. The motors only have 220 hours on them and have been taken care of.

Re: HELP 2000 Carver 350 Mariner Transmission Vibration
Just "looking" at a prop tells you nothing except whether it has any signs of an impact. If it's not tuned to spec, it will cause a vibration. This is not something you can see, it requires shop equipment. A good prop machine shop will scan the prop free of charge and provide an estimate for tuning it. Your cost if the prop is fine will simply be for removal and reinstallation. This way, that piece of hardware can be ruled out as a contributing factor.
They should know that in checking engine to shaft alignment, anything more than .003" off is unacceptable IMO. If they check it properly, they will also be able to tell if the shaft coupler and tranny flange mating surfaces are true. If they don't check this and one is warped, it won't matter what you do with the rest of the hardware, you'll still have a vibration.
Don't forget, simply focusing on one item in the driveline such as checking engine alignment, finding that it's off and correcting, doesn't mean you'll no longer have a vibration. If anything else is off such as the prop, shaft, cutlass bearing, strut alignment, etc., you'll still have a vibration, you might just notice it at a different rpm. All of these can be contributing a degree of vibration.
Keep us posted.
