    Any Suzuki guys that have done rebuilds on the DT V6 2 strokes? The manual says you need special tool cylinder alignment plate where the engine holder goes (under oil seal plate) . it gets torqued BEFORE the cylinders do, presumably to align the cylinders. has anyone done it without it, using...

    Mercury Gen 1 cables to OMC possible?

    I have a new - to - me race boat and installed a XP100 Evinrude. Boat is rigged for gen 1 merc shift/throttle cables. Does anyone make an adapter to use those cables on a 1979-up OMC? I see 33c cables do have an adapter, but can't find one for the gen 1 quicksilver cables. these cables have that...

    Engine building tip regarding gel-seal?

    Someone had told me years ago to put a dot of gel seal on the center main and upper and lower bearing housing surfaces, as it would make the motor alot quiter. Thought i'd try it with my current build, a 2001 V4 looper 135, but where would you put the gel seal on the upper and lower caps and...

    Check valve / recirculation replacements? loopers and crossflows

    Anyone ever try replacing the check valves with el-cheapos from ebay/amazon? The prices are outrageous @ 105ea. plus the ride. I am talking about the recirc valves going from the intake manifold to the cylinders both port and starboard. For example, doing a looper V4 and they take 4 of them...

    Gearcase compatibility - V4 Crossflow question

    Anyone know if its ok to use a 1991 and up lower on a 1989 v4 crossflow? Ive got a gt100 (1989) and a 1993 88spl with a good lower. The driveshafts are different, but I bolted up the 88 spl to the GT100 and it seemed to go toghether fine, but hope the newer gearcase isnt a tad bit longer as i...

    1985 Mercury 25xd starting issues

    Rebuilt the carb (ultasonically cleaned) with a new OEM quicksilver kit. Looked flawless after I was done. New coils and plugs/wires. The motor takes about 5 or 6 pulls to start when cold, and idles at about 1800rpm. initially on starup, it idles ok around 1100 rpm (on hose no backpressure), but...

    To lap or not to lap?

    Flywheel taper on a 93' 225 Johnson. Its hard to tell between rust that matters and just staining. the taper and inside the flywheel are very smooth, but since I take this motor 30+ miles offshore, do you think a lap is in order or not? As long as its clean and dry (i use alchohol as a final...

    60 DEGREE vapor seperator function?

    Been thinking about this, and was wondering why the 60 degree eagle motors have a vapor separator, while the crossflows and 90 degree loopers dont? something to do with the carbs on the 60 degree motors feeding directly to the intake ports? just trying to understand why the engineers put one on...

    Etec 40hp-60hp powerhead swap onto carburated midsection ?

    Examining the adapter gaskets, and was hoping someone could confirm that an etec 40-60hp powerhead will fit on the older midections (1989-2005). the driveshaft looks the same (i believe 92 and up was fine spline on the carbed motors). this project has intrigued me for a while, as etec powerheads...

    40hp vs 50hp looper pistons and rods. Scratching my head!

    Below are 2 pistons. one on the left is from a 1986 Belgian-made 50hp. One on the right is from a 1984 OMC 40hp. Note huge cutout on the 84'. both blocks are the same 326100 series. what's the deal? Further, the rods on the newer 86' 50 have no oil holes on the small end, but the 40hp does and...

    Rod cap alignment: seat themselves?

    I've been pondering this question for a while and thought i'd see if anyone has thoughts on my little theory regarding connecting rod caps on 2 stroke outboards. I only rebuild OMC motors, and use the rod cap alignment tool when needed (NOT on the hand-sanded rods, of course), but this applies...

    Outboard Painting

    I tried searching for this topic as i'm sure it's been beaten to death, but couldn't find much. I'm thinking of using a paint brush or 2 instead of the spray paint i've been using all these years to restore OMC motors. Can anyone recommend a good paint? should it be enamel i'm looking for, or...

    etec 40-60hp powerhead swap onto older midsection?

    does anyone know if its possible to fit an etec 40-60hp twin on an older midsection? i've got a couple options for "older midsections" 1980's and the newer 89' and up ones. i ask because the adapter looks the same, and of course the adapter gasket. i was thinking this would be a great way to use...

    V4 Crossflow carb question

    Does anyone know if I can substitute a metal-housing float bowl for the plastic ones? I have a 110hp from 1986 that uses a plastic one on top, and metal on the bottom. The plastic one on top looks deeper, yet houses the same exact orifice plugs as the metal one. The reason I ask is the bottom...

    upper crank bearing... no sealer?

    So after putting toghether a 1985 70hp (49 cube block), i realized i had a brain-fart and did NOT put sealer around the upper crank bearing head and it's 0-ring. I was going off an old 1979 service manual, and it didn't mention it. Then , when i got back to my shop, was looking through the 1989...
