    150 EFI throttle linkage

    Does anyone have a fix for the throttle rod popping coming out of the lower fitting? This is the vertical rod behind the intake. It was doing it about 5 years ago and a certified Mercury mechanic told they all pop out if someone does a panic stop. About the forth time it happened I replaced the...

    This doesn’t look right to me

    It sure seems like there should be a cotter pin or tab washer on that shaft.

    150 EFI low oil pressure

    I received the attached photo last night. I went out this morning and everything checks out… plenty of oil, no stored codes, and good oil pressure that climbs with throttle. The only thing not checked was a higher power setting because it was on a lift in a slip. Boat and motor are 2 years old...

    Suzuki oil change warning question

    Can the oil change due warning put the motor in limp mode? I was called out because the DF250 was sounding an alarm, had an oil pressure light and would not go to full power. Knowing it had an oil change last fall and the oil on the dipstick was full and clean, I performed the oil change...

    I HATE AUTOMATIC BILGE PUMPS!

    They never fail to fail ON and drain the battery to ZERO volts. Most chargers today won’t even attempt to charge a flat battery and the odds favor the battery being trash at that point anyway. I don’t see a reason to have bilge pumps hard wired to the battery if all they can do is kill the...

    Pontoon trailer bunks…

    They are constantly working loose and falling off. As near as I can tell, the trailer flexing is ripping the lag bolts out. Does anyone know a better way to secure the bunks than the lag bolts through the bottom that the manufacturers use? Options are pretty limited since nothing can protrude...

    502 Bad Gateway

    What causes this? I have been seeing it a lot in this forum the last few days. Reloading the page usually clears it. Using Chrome on an iPhone.

    Tritoon restoration

    I’m thinking about trying to restore a boat that has been sitting for several years uncovered and outside. The 22’ Harris is 12-15 years old with the same vintage Honda 150. - the deck feels solid. -Rodents have had their way with the wiring. They left nothing to repair. -Needs flooring and...

    SX-A thread repair

    Vent plug started fine but never tightened up. What’s the popular fix? Heli-Coil?

    Sticking weather seals

    I dropped a Yamaha seal into the lake when it stuck just long enough to not fall back on the engine a few years back. I glued that one to the middle cover. The Mercurys want to pull up about midway on both sides. I am pretty sure they would come completely off if I did stop and pry them back...

    Suzuki DF175 surging at high power setting

    Just started getting a 1000 rpm surge at high power settings going across the lake. Not feeling a miss. I think about 1100 hours on the motor. - Replaced the low pressure filter. No change. Tank run with no load shows: - High pressure side reads 70 psi when the key is turned on and 40 psi...

    BF200 power loss at full throttle

    New motor last year. 121 hours. Typical clogged fuel filter symptoms except both have been changed. Runs great for about 2 miles at full throttle then falls on it’s face. Let it idle for a bit then go again for a shorter distance. Primer bulb doesn’t collapse. Pumping primer bulb when engine...

    Water in the fuel

    I was called to the dock today to look at a 2017 Monterey that wouldn’t make power but start and idle okay. I automatically pulled the fuel filter and it was clogged with a pale slime and full of water so the engine mystery is solved but fuel filter only had 6 hours use. Where did all of the...

    50hp EFI diaphragm fuel pump pressure

    A friend asked me to look at his 2006 Mercury 50hp EFI. Motor runs okay as long as someone pumps the primer bulb every few minutes. I think I have the problem isolated to the diaphragm pump but would like to confirm how much fuel pressure it should be producing. I am seeing less than 4 psi on...

    Service manual for 7.5 HP

    I’m looking for a service manual for a Mercury 7.5 Hp 2-stroke outboard. I have no idea how old this motor is. Mercury tells me the serial number isn’t valid which is making it difficult to know what parts to order. Serial number on the tag is 6431074. Someone lied to a buddy and told them I...

    5.0 GXi oil extraction

    I checked the oil level before attempting extracting the oil. The dipstick showed full but I am sucking air. I have only managed to remove about 2.5 quarts after an hour last night while the oil was warm and 2 hours this morning with the oil about 50 degrees. I am using a hand pump vacuum...

    4.3 Mercruiser fuel supply issue

    Working one that started out as a “won’t start” on the lake but checked good at the dock after it was towed evolve into “won’t start” after fuel filter change. I installed a primer bulb and it started fine after pumping it up. Power starts dropping off after a minute or so and eventually gets to...

    Yamaha F150 overhauls?

    Are there any known good shops rebuilding Yamaha F150 power heads? Had a rental take a hit from behind hard enough to lockup a cam and strip the belt. One or two outings after changing the belt, the pulley on the other cam broke creating a kickback hard enough to remove the flywheel nut and take...

    2018 Mercury 150 EFI hard to start hot

    Motor has been running great and starts easy cold but go for a restart after it is warmed up and it repeatedly fires and dies. I don’t see anything in the service manual covering the issue. It can be started by giving it a little throttle but something isn’t right for that to be a requirement...

    Fuel use meter?

    I need some way, other than leaving full and refilling when I return, to find out how much fuel is used on each outing. I know about FloScan and it is a nice, across the board fix but it is a little pricey for me. It seems to me that with everything on the modern engines being computer...
