Replacing a Bad Velvet Drive 1:1 with the ZF 1:1 45C Marine Transmission. Subject Boat 1994 MasterCraft. Why Replace and not Rebuild?? Rebuilding the Velvet Drive is nearly as much as buying a new ZF with new 2 year warranty!

I already knew how to do this job. But always good to watch someone with more years under their belt to catch a few tips.

Very informative and well put together video that a novice weekend mechanic or salty experienced mechanic can refresh his/ her skills with and learn from. Thanks for posting and sharing.

Thank you. I removed my velvet drive last season and wish I’d thought to loosen the trunnions bolts on the motor mounts. What a difference that makes!

Great info

What do you torque the installation bolts to?

@romakayak Год назад

I have a Paragon P45 on the back of my engine hangout from 6 x M10 bolts. Should it have a rubbing mounts to take some of the 300lbs weight?

@rontanis1024 Год назад

Not familiar with that gear, consult with Paragon on this one.

This is a bit above my pay grade. What would a boat service place charge for this, parts and all? Assume the boat is a late '80s or early '90s MC Prostar 190. Is it even smart to look at one of those with a bad trans?

@stankthetank9375 3 года назад

Should the drive shaft just pull away after you take out the 4 coupling bolts. Or do you need to loosen the packing nut thanks?

@rontanis1024 3 года назад

No you do not need to loosen the packing nut, in a perfect world the shaft will slide back with little effort after removing the 4 coupling bolts...we don't live in a perfect world, here are some hick-ups...severe out of alignment can cause the coupling halves to bind together requiring persuasion to separate, can also cause major resistance for a shaft rubbing hard against the shaft log, again caused by major alignment problems. There will be some resistance from the strut & packing gland, a little soapy water sprayed there will ease that.

On an older boat do you for sure need to pivot the engine? Doing damper plate replacement and don't want to pivot engine if I don't have to. Thanks for any info~

@rontanis1024 3 года назад

All depends on the boat, if you have room then no you don't have to pivot the engine, if you are avoiding pivoting because you don't want to re-aligne the engine to the shaft, you are mistaken, a shaft re-alignement is required regardless.

@@rontanis1024 Thank you Ron. I can support the engine with straps but if I don't have to raise the engine with straps to get trans/bell housing off I would prefer that.

@TheRepairGuru 3 года назад

Got the new plate installed. Lifted engine & trans with straps. Removed trans & bell housing as an assembly and replaced drive plate. Re-aligned assembly, bolted up and good to go. Thanks Ron for all your helpful videos.

Hi Ron Tanis, recently bought a 1990 pro am ski boat with a 350 5.7l mercury in it and it has no forward gear. Randomly works or if not at all. Any ideas ? Velvet drive ?

@rontanis1024 Год назад

Things to do first, fluid level, check immediately after shut -off before drain-back from the trans cooler, should be at the high mark, after it sits for a minute it may be 1/2" above the high mark, this is normal. Remove shaft cable & manually move shift lever at the trans from full forward , neutral, reverse while in the water, if normal now you have a cable/throttle issue.
