    How does my Evinrude 115 stack up against the old and the new?

    My 1998 Evinrude 115hp (80hp jet) is in need of some TLC and I'm thinking about replacing. This may be where the similarities end but my motor has the same bore and stroke and is a 60 degree looper just like the new etec. Should it perform about the same? I'm looking for max power to weight and...

    Need compression and carb settings info 1998 Evinrude 115hp

    I have a 1998 Evinrude 115hp (60 degree) outboard and I'm looking for a few specs. Compression, idle mixture screw (default turns out), and possibly instructions to fine tune the idle mix from there.

    2008 Mercury 9.9hp 4-stroke starving for fuel

    2008 Mercury 9.9hp 4-stroke It ran great when stored last winter but when I tried to fire it up today it fires up easy with primer but quickly dies. If I keep pumping the primer (engine primer, not fuel line) it keeps running. With some throttle I was able to keep it running without primer...

    What tread does 06 etec 250 use on flywheel for lifting?

    On this motor you install a lifting plate with three bolts on the flywheel. Same holes used to remove flywheel. We have fabricated a plate but don't know what thread the flywheel uses. I tried 8mmx1.25 and 8mmx1.00 but neither wanted to tread smoothly. When the dealer loaded the engine their...

    7 3/8 or 7 5/8 pump on 150-200hp outboard?

    I'm buying a 150-200 small block etec and I'm trying to decide if I want to use my existing 7 3/8" pump with a V6 impeller or upgrade to a 7 5/8". I was told by Outboard Jets the smaller pump would be faster and the bigger pump better for heavy loads. I'd prefer to save money by using my old...

    How heavy should original foam be?

    I pulled the floor in my 1998 Woodlridge 17ft Alaskan and the foam didn't seem to be waterlogged but it's definitely heavier than the purple closed cell foam you can buy at the hardware store. I called Wooldridge and they said the coast guard requires them to use a very expensive high grade...

    Rattle control for new aluminum floor installation?

    I'm installing 3/16" 5052 diamond plate floors in both of my boats and I'm trying to find the best way to keep them quiet. I've heard about caulking but it seems messy and it would be a pain if I ever had to peal the floors out. I've thought about thin foam rubber strips. I also heard...

    1/8" or 3/16" Aluminum Diamond Plate Floors?

    I'm looking to replace the floor in my Wooldridge Alaskan and I'm curious if I can get away with 1/8" aluminum diamond plate. It came with 1/2" plywood and has longitudinal support with 14" separation. If it were just a question of money I'd go with 3/16" but it's going to add 49lbs (104 vs...

    Is 40hp enough on 16ft Hewescraft

    I just bought a 1994 16ft Hewescraft Sea Runner which is supposed to weigh 900lbs empty. I plan to use it on the Kenai River so I can only run 50hp max. I already have a spare 2007 40-hp Honda 4-stroke and I'm curious if it will be enough or if I should start looking for a 50. Maybe something...

    Did trailer manufactures commonly bronze trailer rails back in the day?

    I have an old 1964 Long trailer which has several layers of old paint. I accidentally scratched some of the paint off one of the rails and the metal looks like it's gold plated. Can anyone recall bronzing trailers or some other type of plating? Edit: Ooops wrong section. Mods please move.

    How does law enforcement interpret jet rated hp?

    I have a 17ft Wooldridge and I'm trying to make it upper Kenai legal which is 50hp max. My current motor is a 115hp powerhead but rated and factory decaled 80hp because it was a factory jet. Do they go by the powerhead or by the net jet rating? Does it make a difference if it is a factory...

    Need valve shim info for Yamaha F75-100

    I'm having a hard time finding a shim kit for my 1999 Yamaha F100. Anyone know where to buy one? I was hoping they would be 7.48 or 9.48mm but they are larger shim over buckets. I'll pay the dealer $15 a piece if I have to but in my experience it becomes a back and forth nightmare if you...

    Want to update 1999 Yamaha F100 to 2013 Paint & Decals

    I plan to repaint my 1999 Yamaha F100 and I figure why not make it look like the new models. I'm looking for paint code information, suppliers, equivalent brand codes, and aftermarket decal suppliers (latest design). As far as I can tell the new F90 is externally the same so I was going to go...

    How to remove valve cover? 1999 Yamaha F100

    I'm having a hard time removing the valve cover. It looks like I have to remove the cam gears to get it off. Is there a trick to it? I really don't want to remove the gears if I don't have to.

    Oil injection needle valve adjustment. 1998 Evinrude 115hp

    I need to know where to set the oil injection needle valves on the throttle plate. I wrote down the turns out but between the two they didn't match so I was hoping someone could give me a good starting point. On the left bank I ended up with 6.75 out on the top and 7.125 out on the bottom.

    1998 Evinrude 115hp Looper 80-83-82-84psi low compression???

    I just tested the compression on a newly acquired 1998 Evinrude 115hp and I'm a little concerned. 80-83-82-84. I heard the loop charged motors test low but 80 still seems really low. Tested at WOT.

    99 Yamaha F100 Is the hose on the front a vent??

    There is a plastic nipple right in front of the shift shaft on the lower unit that appears to be a vent that attaches to a hose run up under the cowling. As far as I can tell it doesn't vent anything. I tried to blow through it but it's sealed. What exactly does this port do? or do I have a...

    Does cooling water only exit the pisser?

    I'm fairly new to outboards and I'm curious if all cooling water exits through the the pisser or if some comes out the exhaust. I ask because all my old jetskis had pisser outlets but also directed water into the exhaust manifold for cooling.

    How much pitch? 15ft Whaler with 50hp

    How much prop can my boat handle? 15ft Striper with fuel injected Yamaha F50. 1.8:1 final drive, estimate 8-9% slip. I get 32mph on gps with my stock 11 pitch at 6000rpm. It pulls hard until it runs out of rpms. I want to pick out a speed prop but don't want to be too aggressive. If setup...
