Continuous beep is overheat alarm. Intermintent beep is low oil. I have seen the electronics module that controls these alarms go bad and sound the alarm erroneously. If it is overheat, which is...
I have a 1991 Merc XR4 150 S/N 0D007758
My engine sucks a little air when I trim up the engine so I decided to lower the engine 3/8". I loosened the 4 side bolts until the washers underneath are...
I'm no expert, but loaded up I think you are in the lugging it problem area. According to the source below max rec rpm range 150 Opti is 5250 - 5750, though they don't list your specific year. ...
If you use synthetic oil like Amsoil you don't have to worry about fouled plugs or smoking. Racing motors mix at 40 to 1.
I've got some sort of loose connection under the cowling of my 1991 Merc XR4 150 S/N 0D007758. When the loose connection acts up the dashboard is dead (fuel gage doesn't register), the warning horn...
Is there a place somewhere on the gearcase where a valid Part Number can be found?
I forgot to say it is a 2:1 gear ratio and has 8 splines on the driveshaft.
I'm not aware of a gearcase having a S/N so I can't post that.
I have a 20" (Long) gearcase with 1655-7332 cast into the top of the gearcase right where it attaches to the midsection. I know it...

I wanted to do a good test of the low oil alarm on a 1991 Mercury XR4 150. I took the oil cap off and carefully and gently put about half of a toothpick exactly the right length between the cap and...
I'm concerned that somewhere in the overheat sensing system, either the sensor itself or the wiring, that something is not working. It's definitely not the horn itself because if I put 12 V on the...
I've got an electrical problem I can't solve. Maybe a whole new wiring harness would be the way to go.
I have a Bumble Bee bass boat I switched motors on last year. I took off a 1991 XR4 150 with the original oil injection still working fine and put on a 1996 200 EFI that had already had the oil...
I think the reason so many people with Mercury V-6 engines are coming to this board, and the reason I came to this board, is because of the wording of the "Mercury - 2.0/ 2.4/ 2.5 Liter High...
I have a 1991 V178FD and I love it. Bumblebees haven't been made in so long. I heard they went out of business when Triton and Stratos started a thing called the "Preferred Dealer Program" where if...
I have a Bumble Bee bass boat I recently switched motors on. I took off a 1991 XR4 150 with the original oil injection still working fine and put on a 1996 200 EFI that had already had the oil...
Phoenix boats are the new Bumblebee boats when Phoenix bought the company. Here look at my 1991 Bumblebee V178FD. It still looks brand new. It has given me fantastic service for 28 years and will...
I installed a water pump kit for my first time on a 1996 Merc 200 EFI. Before installing the kit, for the past 14 months since I bought the boat water flowed just fine. I'm mechanically inclined,...
Gamblers are heavy and fast. Bass and Walleye Boats magazine tested a 1600 lb Gambler with a Merc 250 Pro XB and it did 86 mph.
I swapped engines on 2 bass boats and put a 1996 200 EFI on my bass boat. My original engine had the oil injection for oil, but the 200 EFI already had the block off kit applied for premix fuel. I...
I was able to tap it off with a hammer and punch. Thanks for your help.
I can't figure out how to take that hub off. There's no side screw, set screw or jam screw. If it spins off I can't figure out how to restrain the steering shaft well enough.
I am replacing the Teleflex rotary dual cable steering on my 1991 V178 FD Bumble Bee bass boat. I haven't received the replacement kit yet. But I wanted to get the old steering hardware off so I am...
