Hey all,

I'm a newbie to inboards here. So far from a handling perspective I think they're great!!! I'm just trying to be proactive here and find out from anyones personal experience what type of maintenance is involved with the transmissions. I hear they are extremely expensive to replace and want to make sure that I take proper care of them so they last a long time. The boat is a 93 330 Sundancer powered with twin carbeurated 454's. Its an aft cabin boat hence the transmissions are V-drives. Thanks in advance.

Check the fluid levels periodically. Even know I put 2 new Walter V drives in my boat one kept losing fluid it ended up being a damaged seal that occurred during the re-power. Yes make sure your shaft flange and transmission flang bolts are tight. In my case I have 2 warning lights to make sure I have proper water flow through the drives. The lights are only on at idle. My V drives and transmissions are separate units.

Yes....check your fluid EVERY time before you go out.......the tranny fluid runs thru a cooler.....cooled by salt water. You want to make sure the two fluids remain seperate.

I had a cooler let go from one day to the next.....good thing I caught it ....before it did any damage. I now check oil in engines and trannys DAILY..............

you should get an owners manual and reference the fluid change interval reccomended by the mfg. regardless of how many hours of use specified on the interval, i would change the fluid and filter screen at least every 3 years. as others have noted checking the fluid and a visual inspection every time you use the boat is prudent.

There is a special procedure to check fluid level's.
Different when the trans is hot/cold.
Run boat for at least 1/2 hour, get motor and transmission fluid HOT.
Shut down, wear gloves, and read level on dip stick.
If low add just enough to get to full line
If you check the fluid cold you starve the tranny when on plane.
Not doing this just cost me a bunch.

vic,

Where are the filter screen? Lets presume we are talking about the port transmission and that once I find that filter I will know where to find it on the other transmission. I do not know if they were changed last year (different owner) but I know that my mechanic did NOT change them this year. I would like to address this just to make sure I stay on top of things. Thanks a bunch.

I believe the 630 & 800 models have a small cylindrical replaceable filter on the top stb. rear of the transmission, not sure any of their others have one. It could also be a good idea to backflush the RW transmission cooler every year or so as weed has an uncanny ability to get past those tiny RW intake strainer holes. I was just surprised at the stuff that I just flushed out of my 2003's downstream of good Groco RW strainers.

About Time - My tranny dipsticks have separate markings for fluid levels when hot and cold for exactly this reason.

The Hurth tranny filters are stainless steel and are washable. Be careful of the O Rings.

Mine too , on transmission & crancase sticks.. I made the cold line after 1st confirming proper level when hot. On my VD's the levels are nearly the same.
