First, many thanks to all for the help and support with issues in the past. Unfortunately, this might be a doozy :confused:

Launched the '92 Sea Ray bow rider for the first time in about a year. In the months preparing to head out: I replaced the T-stat, impeller, motor and drive oil, rebuilt the top-half of the carb (see thread located here), charged the batts, and did several runs on the muffs w/ no problems.

Out on Saturday, we had a blast!!:D Played for approx 5hrs between sking, cruising, floating, and swimming. Boat ran like a champ with no issues, hesitations, or complaints...

We left a cove to head back to the ramp and call it a day. Once on plane at about 3/4 throttle (3500 RPM'ish), and underway everything was fine. As I was about to give it a bit more, it suddenly sounded like we'd spun a prop.:eek: I'm confident we didn't hit anything, and checked the prop for debris once stopped. Restarted the boat, ran fine, but wouldn't go into gear. Removed engine cover, and all linkages seem to be normal and operational. With engine off, put into gear and the prop caught as it normally does. Restarted again, but it just reved instead of going into gear again (couldn't try to start while in gear due to nutral safety switch). Tried to reverse, and it sputters/dies.

Although it wasn't until I'm raising the outdrive for the tow back, the temps were fairly high at this point (which seems to say the impeller wasn't spinning during my attempts to move). :facepalm:

Not sure what might have happened, but any and all insight is GREATLY appreciated!!! Just trying to get an idea what I'm up against before tearing things apart :eek:.

Much appreciation to '$tole It' for the ride back! Lunch is on me next time we meet on the lake!!

EDIT: '92 SeaRay 200 BR, 4.3 Mercruiser w/ Alpha I outdrive.

Sounds like you may have spun a coupler. Did you smell rubber and did you check your allinement when you installed your drive ?

Smell rubber...no, but it's a breezy lake. As far as the alignment, I only dropped the lower half so there's not much to re-assemble. What are you refering to by the 'coupler'?

Start it with the muffs on and see if it goes in gear and spins the prop. May have broke the drive shaft in the lower which runs up to the top and also turns the waterpump. #10 in this diagram. Some times they break on the top where the splines lock into the gear in the upper.

Lake Pleasant, Apache or Canyon Lake?

The first thing to check is the prop hub. (Or try a spare prop)

If that doesn't work, look in the back for metal particles or rubber powder. (coupler)

If it's the coupler, plan on removing the drive and engine (in that order)

Otherwise, you may have something wrong with the drive.


Sorry about that,


Rick

How often do these things just break? We were underway with little load on the boat. Anyway, I haven't dropped the lower to check anything yet. If it is the coupler, is there any indications other than tearing off the outdrive to check (like rubber bits or shavings in the outdrive oil)?

Let me know if you need help to check it out. I'm in East Mesa and frequent Saguaro and Canyon lakes.

Couplers last a long time if the engine is aligned properly- the worse the alingment, the shorter the liftspan of the coupler. I had one on a 454 with Alpha SS that went 1500+ hours- I replaced it when I did an engine upgrade, and it looked fine.

My last one went 39 years. They won't last long if the drive is not aligned though.

It has nothing to do with outdrive oil........You might be able to see if there's metal or rubber powder though,.. The coupler is bolted to the flywheel on the back of the engine.

look in the back with a flashlight. You a flyinguy? you fly something?

About the same frequency parts on a 19 year old car break .....

I was refering to 'pickelinjim's suggestion of the lower driveshaft breaking at the splines.

Anyway, I have no idea what the alignment's been since I've had it. The first prop I removed from it was a direct connect style, so there's at least 15yrs of whatever anyone hit transfering stress to all shafts, u-joints, coupler, etc. I suppose I'll just start at the prop and work my way up from there.

You a flyinguy?

Yea, I've got a few laps around the patch. Not professionally anymore, but still take on a student or trip here and there.:D

How much gear oil did you get in there?

Gear oil was full, I'd just done the impeller a few weeks prior. I don't believe there is a any binding within the outdrive, but will check if there's time to pull it this weekend. The biggest concern is that I REALLY REALLY REALLY don't want to pull the engine!!!

how much time have you put on the boat since your impeller change??

did you pressure test the drive before filling it with lube??

you may not be pulling the engine - if you shredded the upper gears due to a gear lube loss

I doubt that to be the issue. It'd ran for about an hour on the muffs to charge the bats a week prior. We were swimming all around the boat a good part of the afternoon, spent an hour attempting to get a couple skiers (rookies) up, and didn't notice any leakage at all. When I did the impeller change, a full capacity of oil drained. When whatever the issue is happened, we were on plane underway and it just suddenly started to over-rev while ceasing to produce thrust. No noise or other sounds during or on subsequent attempts.

I'd very much love to think I spun a prop hub, but troubleshooting on the lake has ruled that out. Now my mind is starting to think of all the other things I can do to the engine if I have to pull it (hey, if it's already out anyway...).

I think the first thing I would do is start it on the muffs. Then shift to forward and see what the prop does. Then try the same in reverse. This will at least tell you if the vertical drive shaft is turning. If it's not remember that shaft also turns the water pump so don't leave it running long and watch your water temp gauge.

all it takes is a few hours of running around on the lake and your down a few ounces of gear lube - no indication of imminent damage and your top gears are shredded

its probably the easiest to check, pull the four top cap bolts on the drive and look at the gears

if you didn't pressure test the drive after reassembly, and it sounds like you didn't, how can you be so sure that the drive gears are sound??

Did you ever figure out what happened? Same thing happened to me yesterday, I plan to pull the outdrive apart this afternoon.
