    Honda 150hp Lower unit compatibility

    Hello, I could use some help deciphering the differences between a 2004 150hp lower unit and a 2018. According to boats.net, the gear case part numbers are different. Looking at my 2004, there is a bearing carrier on the prop shaft that the newer lower unit does not have. Can I bolt on the 2018...

    (150hp) Need help deciding between counter and regular lower unit

    Good points. The leaning to one side and the location of the captain seat (starboard) may be a deal breaker for the LH lower unit as my boat is a pretty light (2800 lbs w/o motor and fuel) 22’ aluminum with a shallow deadrise (former inboard river boat—14-16 degree) so I can see it being prone...

    (150hp) Need help deciding between counter and regular lower unit

    Wow, so there really is not much of a difference between LH and RH lower units. To clarify, my RH lower unit is bad and I’m shopping for a new one. I’m considering a LH lower unit. Both LH and RH use the same gear case and shaft but the gears inside are different or just the placement of the...

    (150hp) Need help deciding between counter and regular lower unit

    Hello, I’m on the hunt for a new lower unit for my 150hp. I’ve narrowed it down to two units. Could you let me know which one you would choose? #1 counter rotating with nice stainless prop. 500 hours. Nice guy who said it ran great before the powerhead failed. Exterior is clean. Some corrosion...

    Bf-150 How to Remove Driveshaft

    Update: I cracked the water pump housing mount sidewall on lower unit trying to pry the water seal housing. Maybe not too bright on my part or the wall was weakened by corrosion. Anyhow, I’m on the lookout for a new lower with a 25” shaft.

    Bf-150 How to Remove Driveshaft

    Thanks Jgmo and Ian for the help. I found a manual via eBay download ($15). The water seal housing pops right off but mine is pretty corroded. I spoke with a local Honda repair shop who said I may be in for a battle to remove the water seals if there is corrosion. He said it may be easier to get...

    Bf-150 How to Remove Driveshaft

    I think I found the solution. Looking at boats.net and the part under the water pump housing, there is a seal that gets pried up. With all of the corrosion, it was tough to see the pry tabs near the 10mm bolt holes. I plan to drench it in PB blaster and Free All and add a little heat and try to...

    ‘90 Yamaha 175hp no power/start

    Hello, I picked up a 1990 Yamaha 175hp and am trying to get her running again. I’m new to outboards and kind of clueless. This motor was sitting on a pallet not rigged up. Had some loose wires at motor. I hooked the main black harness cable coming from ignition/control box to the motor. Hooked...

    Bf150 Change 20” to 25”

    Hello, I just picked up a 2006 Honda 150hp. And upon checking the the Bay Manufacturing site, I learned they do not make shaft extension kits for Honda. The dealer made it sound like a real pain to change a 20” motor to a 25”. They have to pull the power head and change a bunch of expensive...
