    2004 Bf25d

    I have this motor on my pontoon. Last fall when I took it out, I thought I ran out of fuel when I put it on the trailer. I put new gas in this spring and when I put in, it was very hard to start...harder than usual. Now, it won't go above 3100 rpm. I drained the carbs, put a portable tank on...

    Rigging a starter button??

    I have a 1988 20hp that I am going to rig for a tiller. It is an electric start remote model. I was looking at BRP's site and saw the setup for a tiller starter. My question is, since I didn't see where you could get the whole setup in kit form (ala-cart) could I rig up a pushbutton starter for...

    Another head gasket ???

    Just got the new head gasket for my 92-95 2 cyl 30-35hp motor. This one is a Sierra and is shuny and a but tacky. Are these made to go on without gasket sealer? The manual says to lightly coat the gasket but I was wondering if sealer would mess up one that doesn't require it??

    Gasket cement

    Getting ready to put the new head gasket on my 35hp 2 cyl. 92-95 Johnson. When I rebuilt it last year I used Johnson gasket stuff for it like it said in the manual. I was wondering what you guys use. I can't see on the old gasket where any water or exaust leaked on it and was wondering, if the...

    1995 35hp Johnson 2 cyl.

    This is on the AML35D....I thought the plugs had been steam cleaned so I went and bought a new compression gauge today. The motor is in a shop at about 65 degrees, I took out both sparkplugs, gave it full throttle and pulled till the gauge wouldn't go higher. Top cyl. was 100 lbs and bottom was...

    Aml 35d

    I rebuilt this thing a year and a half ago and just got it all back together in Oct. I ran about 12 gallons of 25:1 through it going by the manual for breakin. I don't think it has 20 hours on it. It ran great up to the last time out a couple weeks ago and seemed to sputter at idle quite a bit...

    30 vs 35 2 cylinder

    I just finished getting my Navy Seal motor all buttoned up from the 2 year rebuild..and It seems it is really strong. My question though is this. Every parts list I look at has identical part numbers for the 30 and 35 hp 2 cylinder 2 strokes. I went through BRP's parts lists and my 2 factory...

    BF25D impeller change

    Just got a pontoon with a 2004 Honda BF25d engine and want to change the impeller. Haven't had time yet to get a manual (the dealer didn't have one). What are the steps for removing the lower unit? Does the shift rod have to be disconnected by the power head? Should it be in F-N or reverse...

    1967 merc 110

    I found a new 6 spline prop and some other 6 spline that are 8"x 8 pitch..they look like they are off a smaller motor..do you think they would fit the 9.8? Or were the shaft diameters different? I'd like to find one with a smaller pitch since I think the one I have is preventing the motor from...

    Another 1967 9.8 ???

    When did Merc start using an 8 spline propshaft? And..is it possible to put one in, in place of the 6 spline that I have? Would I have to change the driveshaft or pinion? I see all sorts of props for 8 spline but very few for 6. Thanks in advance for any info.

    1967 9.8 air?

    I was going to ask this last summer, when I have the hood off my 67 9.8, it seems to be WAY more potent than when the hood is on. Higher top speed, quicker acceleration, idles better. The exaust gasket isn't leaking so it isn't smoking itself out with the hood on. Is there a way to get some more...

    1967 merc 9.8

    I wonder if I pulled a real boner..I was having a lot of yellowish colored oil dripping out of the prop area and figured it was unburned gas/oil. I changed the lower unit oil the other day and it was very dark gray/black so I don't think water was in there...but...I pumped the oil in, put the...

    1967 Merc 110

    Just got this motor on my duckboat. It has sat for about 1 1/2 years since I got it and I don't know how long before that. It started right up and I have been running some sea-foam through it. The telltale is weak so I got an impeller kit, gas pours out of the carb when I tilt it up so I got a...

    Honda 9.9 carb gas spewing

    Just got my 9.9 out after about a year and a half..I think it was stored on the wrong side as oil came out of the carb. I took the carb off, cleaned it by pouring gas into all the holes. Squirted gas in a vent thing at the top and into the screw hole by the overflow tube on the bottom. Clean gas...

    Adhesive M

    As I was putting my motor back together, the manual called for OMC adhesive M for the bypass cover. I used the gasket sealer/maker on it. Now I am a bit concerned after reading another post where it sounded like adhesive M is the ONLY thing to use in specified applications. Other than that..I...

    Installing Boyeson reed tricks?

    Getting my 1992-95 Johnson 2 cyl 30/35 hp ex navy seal powerhead back together and all was going well, got to putting the Boyeson reeds on the reed plate and am having a fit. The instructions are vague to say the least. It say's "remove the tape from the back of the petals..I did and now have 4...

    Gel Seal

    The manual says to lay a bead around the block inside the bolt holes..then to spread it out evenly..what do you guys use to spread it out? Acid brush? Also, what can I use to seat the lower seal into the race besides an OMC seal installer tool? I ruined a new one yesterday and need to order...

    30hp lower bearing

    Can't remember which one of you fellows said to heat it to 250 in the oven..I set my crank in the garage overnight 10 deg and put the new bearing in boiling water for about 4 minutes and it slipped right on..I put build up grease on the shaft first. The heat from the bearing looked like it dried...

    What are your thoughts

    Having a discussion on another site about starting the engine for a few seconds after it's pulled out of the water to get rid of any water left in the motor to keep it from freezing.Not sure if it's anywhere else on the board here or not. Thanks.

    Saga of the 30 hp rebuild

    Well..I have been procrastinating about sending my block out to be bored for new pistons. Meanwhile, I just picked up a brand spankin new bare block with intake manifold for little above what machining would cost. Is there any prep that is needed on a new block before I put it together? There is...
