    Honda BF150D internal anodes

    Hi, My maintenance manual says to check/grease the internal anodes on my 2023 BF150D. It doesn’t give the locations or how many there are. I know of the two that are easy to access on the starboard side of the motor. Are there only 2 on this motor or are there others as well? When it says to...

    Idle 2001 Mercury 150 carb

    Hi, I’ve done a ton of research, read the manual, and I’m still slightly confused. I set the idle timing and max timing by following the manual and set it to spec but my idle is still around 1400 rpm. The manual and forums say to adjust the screws on the carbs, but when I do that I don’t notice...

    2001 Mercury 150 saltwater series crankcase cover stuck

    Hi, Does anyone have any suggestions or tricks on how to get a stuck crankcase cover off? I removed the powerhead, removed all the bolts holding the crankcase halves together including the top and bottom covers, and it won’t budge. I’ve tried prying at the pry points but haven’t had any luck...

    2001 Mercury 150 Saltwater Series (carb) midrange bog after extended running.

    Hi, I have been trying to trouble shoot this problem for almost a year now. I have a 2001 merc 150 that runs great for hours, but eventually starts to bog at midrange rpm. If I run the motor continuously for 3 or 4 hours, I can only drive around idle rpm or WOT. Anything in the middle bogs...

    Lost spark on cylinders 1, 2 and 5 (2001 mercury 150 carb)

    Last week I noticed my WOT rpm drop from 5500 to 4800 so I checked for spark and compression. All 6 cylinders were between 120 and 125, and every cylinder had spark. Today, I was out on the water and lost spark in cylinders 1, 2 and 5. I assume these problems are related. On my way back to the...

    Engine RPM drop

    Hi all, I have a 2001 mercury 150 carb saltwater series and a new issue just started that I haven’t had in the past. The motor runs fine and gets up on a plane no problem. Also, it can maintain 4500 rpm for as long as I want it to without any issues whatsoever. When I pull the throttle back to...

    Prop shaft seals?

    Hi all, when I pulled my boat in the fall I drained the lower unit and there was a bit of water in the gear case. I hit bottom pretty good at one point in the year and I’m thinking that is when water started to come in. Before the season all seals were replaced, so I don’t think it would be one...

    Bleed system

    Hi, just wondering if there is a correct way to install the bleed system check valves. Is there some sort of sealant used to make sure it stays in and doesn’t leak?

    2001 mercury 150 carb 2.5L vs same year 200hp?

    Hi, I’m currently doing a complete rebuild on a 2001 merc 150 carb, serial number 0T266256. The motor is at the machine shop currently and the guy working on it says it looks identical to his 200. He asked me if it was actually a 200 and someone before me just replaced the cowling with a 150...

    Boyesean reeds & porting

    Hi again, looking for some opinions. I’m doing a complete rebuild on a 2001 150 Mercury Carb. My marine mechanic recommended that I port the engine and install boyesean reeds to increase performance. Is this worth it? He said I’d gain 25 hp but I don’t know how accurate that is or the benefits...

    Can this be fixed?

    Can this be repaired or do I need to get a new crank cover? Can I get a new crank cover or will it not be an exact match to my block? I have a 2001 mercury 150 carb.

    Hi, i sucked up quite a bit of sand a couple of days ago and my engine started overheating within a few minutes. Since, I have changed my thermostats and water pump, and flushed my engine. At first water could not exit the telltale but I stuck a piece of wire in there to clear it. Now it...

    2001 mercury 150 sluggish acceleration

    Hi all, i have a 2001 mercury 150 saltwater series that has been becoming more and more sluggish when accelerating. When I put it up to full throttle it doesn’t have the punch it did in the beginning of the season. It will start off sluggish and then suddenly it will get all of its power back...

    Low RPM/Rough idle when in gear

    Hi All, I have a 2001 Mercury 150 saltwater series and about a month ago I replaced the lower unit (not sure my problem is related, but I have a feeling it is). When I shift into forward or reverse my RPMs drop from about 900 to about 600 and my engine seems very unhappy. It shakes a little bit...

    Sudden oil consumption

    Hi, I have a 2001 2-stroke mercury 150 saltwater series motor. To begin the season the boat was going through the "normal" amount of oil, but recently it has been guzzling it down. I would say every hour or two of use I'm adding about a quart of oil. I cant find any leaks anywhere, and the motor...

    Hi, I’m looking for a cockpit enclosure (don’t know if that’s what it is called) for a 2000 proline 20 walkaround. Anyone know where to get something like this? I’m talking about the sides with windows that zipper to the Bimini top so the driver and passenger stay warm and dry in bad weather...
