Help, can you tell me what went wrong?
 

Ok so i was cruisin along on sunday in the Nordic. I was going about 40mph. I decided to hit the throttle and speed up, when I did there was a sudden loud beep. The boat slowly came to a stop and since the throttle was still engaged the motor just reved up. So I put the boat in nuetral and opened the engine compartment. Smoke was coming from the belt/pulley area and it smelled like a burnt serpentine belt. I check to see if my boat still goes into gear, which it does. It will go into gear but as soon as I give it some gas it does the same thing again. boat will go no where,rpms will jump up,motor will rev up and the smoke will start up again. I dont think its a spun prop.What do you guys think? Bearings?coupler? Impellar pump? One last thing, its a 496 with a bravo, boat has 55hrs on it and was just serviced. Oil change and drive was checked for alignment. thanks

Sounds like you spun a coupler, if you had fried an impeller it would have overheated and you would still be able to move.

If its the hub which it sounds like , I dont think a 496 has enough power to do it. I figure ya hit something or theres a engine misalimnt that made the hub spin.

Or the drive seazed [low oil?]and locked up the drive and spun the hub.

just guessing :drink:

I was still able to idle my boat back on to the trailer.

My guess-Coupler
Similar thing happened to me on my Nova years back outside the Golden Gate.

Motor mount collapsed, caused engine/drive misalignment and spun coupler-towed in at 125.00 per hr by Sea Tow @ 5mph for 6 hours...ouch...Wife still reminds me on the expense not including yanking motor.

Good luck hope it works out 4u

Noticed you hit your 100th post. Guess you must be getting over that "bashfulness" and just leaping into conversations nowadays....:D :D

Re: Help, can you tell me what went wrong?
 

i'll second that... or 50th it or whatever, spun coupler

Re: Help, can you tell me what went wrong?
 

The coupler is probably not slipping until it has a heavier load put on it.

I don't know about you guys but I think its the coupler???? :evilb: :evilb: :evilb:

LOL, yep im on a mission to be a post whore like my pal
"PITAM"!! :cool:

Re: Help, can you tell me what went wrong?
 

I resemble that remark....:drink: :drink: :D :D

Re: Help, can you tell me what went wrong?
 

it's the Johnson rod, held in place by the kinebling pin:D


or by duct tape in the JC perf motors:evilb:

Re: Help, can you tell me what went wrong?
 

I read JC's shop manual and it said to just jam some duct tape in the coupler and it should be just fine again. :D :D

Re: Help, can you tell me what went wrong?
 

How much did you end up spending on the repair itself?

Re: Help, can you tell me what went wrong?
 

Ok so it is the coupler....Who in so cal do you guys recommend for this kind of work and knows what their talking about? I know the motor has to be properly aligned and check the motor mounts for sagging right?
