    BF200 power loss at full throttle

    They finally got the boat off the lake. I spent all morning trying to figure out how to make a connection with my fuel injection service kit only to find out it isn’t an easy task unless you buy the Honda tool. It threads into a standard 6mm(?) hole and I have nothing that can do it. I...

    Honda BF60 Dies Above 3kish RPM

    HEADS UP!!!! I just learned the Harbor Freight fuel injection service kit does not have the connector needed to connect to a new BF200D I need to check. I do not know about your 60hp but this is the first time I didn’t have an easy connection. Might just be a Honda thing.

    Honda BF60 Dies Above 3kish RPM

    I can’t think of anything you haven’t covered without going into the electronics of the motor. Maybe it is losing the signal to the injectors for some reason. Throttle position sensor?

    Honda BF60 Dies Above 3kish RPM

    Not so on all fuel injection systems. I was able to install a portable tank with a primer bulb on a Mercruiser equipped boat that had a failing injection pump to make it run good enough to drive the across the lake and load it on a trailer. The boat would run good for about 2 minutes after...

    Honda BF60 Dies Above 3kish RPM

    I bought a harbor freight fuel injection test kit a few years ago. It is essentially a pressure gauge with adapters for nearly everything and has served me pretty well working 6 or 7 different brands of marine motors for no more than it cost. It does sound like low pressure is a long shot...

    BF200 power loss at full throttle

    Good ideas on both but any restriction upstream of the primer bulb would cause it to collapse. The boat had an aftermarket flowmeter installed this spring. I might try bypassing that. The boat was rigged with 5/16” fuel hose. That seems small for 200 HP. All of the 150 HP Mercurys and...

    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...

    pdf service manuals

    I keep my pdf files on my phone or tablet so no need to print and carry pages to the shop. Most of my manuals are paper and live in the shop but I have some Mercury, Yamaha and Volvo on my phone.

    Water in the fuel

    The same thing as the cap on a lawnmower. The vent is covered by the outer cap.

    Water in the fuel

    Condensation in a boat fuel tank isn’t any different than condensation in any other fuel tank or can. The easiest way to prevent condensation is to minimize the amount of air in the tank. I know one of the outboards (2018 Monterey) has a vented cap. It’s all I could find to fit the threads in...

    Water in the fuel

    Fuel supply okay. 16 boats running on the same supply. I would be seeing more problems across the fleet if not. Not sure on gas cap but I think it’s original to the boat (2017).

    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

    I am sending the boat back today. The new mercury lift pump is putting out 3-4 psi which matches the old pump except for the needle on the gauge is steady now. I attempted to order a manual for this motor through ebay but it got cancelled an hour after I paid for it. The vendor’s canned excuse...

    2006 merc 40 4 stroke

    I think buy a basic fuel injection test kit for ~$45 before spending $600 on a high pressure fuel pump that may or may not be needed. https://www.harborfreight.com/basic-fuel-injection-service-kit-64939.html
