My outboard runs for 15 minutes and then stalls and wont start until it sits for 45 minutes. Is this a symptom of running too lean and a sensor shuts itself down? Maybe temp? It doesn’t smoke at all and i have a oil reservoir. Thinking of draining that and just moving to premixed fuel. Thanks

Thought the alarm was low gear lube sensor and ignored it for about 8 minutes until I glanced at temp gauge and it was way up and smoke was coming from engine compartment. I shut down at that point. I know, stupid but...

Electrical system shot due to muskrats chewing all wires on 1988 200hp Yamaha
Tried to move boat today (it's on a trailer) but could not get the motor to manually tilt up. Tried to connect jump box directly to yellow / green trim wires but appears that trim motor is shot.
Can't trailer this...

'88 Yamaha 200hp
The little buggers chewed through about half of all of my wires about 18 inches up from where they enter under the cowell.
I'm sure I'll have to fix them one by one (looks like about 20 total). They appear to fairly well color coded so the identification should not be too...
Mercruiser 454 EFI MAG Engine serial: 0F802536 in a Baja
The electronics that open and close the plates that divert the exhaust through the hull have stopped working. Know of some good trouble shooting steps for me to follow?
Thanks
Bought a used pontoon with a 90 hp Mercury sn# 0G556703 that didn't have keys...<br /><br />Thought it would be simple to change the ignition switch.<br /><br />Well, it has the "push to choke" feature and it has the following configuration in a counterclockwise order:<br /><br />red /purple<br...
88 Yamaha 200hp. When I try to start or raise / lower trim there is only a temporary clicking coming from the relay assembly. This is the point of where the main wires from the boat connect under the cowell. <br /><br />Took the cover off this 2" x 3" box (which on Yamaha's parts diagram is...
I'm having what I believe is a prop slippage problem in a '96 Baja with a 454 Magnum Bravo One.<br /><br />I've searched the posts but have not been able to confirm that this is my problem.<br /><br />Occassionaly when I'm coming out of the hole the rpm's increase perfectly fine but the boat...

Looking for a good mechanic around Lake Wylie. Have a 1996 big block with efi on a Bravo I. If wvit100, member 9246 is out there I'm hoping you'll know of one or more.
454 starts, idles, and runs fine up to about 25 mph. It then will periodically hesitate for about 1 second at a time and goes completely quiet as if someone hit the kill switch. Began a couple of months ago at around 45 mph and is getting worse. Now it sounds as if it may stall if I do not...
