    v4 crossflow setting timing

    since i don't have a test tank, for the high rpm portion, what about lashing it down to the trailer good and tight, backing her in to at least anti-cav plate depth, chocking the trailer tires, and letting her rip? or is there another less dramatic, shadetree mechanic way? FWIW, it's a '75...

    boat-side round red connector?

    i'm looking at a '93 115 crossflow that will come with no boat-side harness or remote control. this will be going into a little fast boat where i really should convert it to a foot-throttle anyway, due to needing two hands on the wheel when it gets into the mid-50's and beyond. so i was...

    90's era 48hp twin, dies at high rpm

    trying to help a friend with engine troubles... it's a 90's era evinrude twin cylinder, 48hp when you run it up to near max rpm, it just dies. it does this on the muffs, too. if you're quick and can bring the fast lever back down to idle, you can keep it from dying, as it idles fine static...

    rot stop idea... comments?

    i've got a small, 16 foot performance outboard powered boat that due to some shoddy workmanship in the past is getting water to the transom and the stringer. as a small boat, it only has one stringer. anyway, everything is still strong and solid right now, and i check it every time i go out...

    it was the tach! and other ramblings

    back around the beginning of the year, i launched a thread about how deep to run my 1975 v4 crossflow, 135hp, on it's light 16 footer, sport hull. turns out i had been running it too deep. there is a plate above the anti-cav plate that i learned was there for spray control. i had my motor set...

    proline 23 quality???

    i've got a friend who loves the ocean, but knows next to nothing about boats. and i know next to nothing about boats bigger than 16 feet... except to be wary of wood that may have become wet and rotted. so, my buddy's main objective is to get a slip here in santa barbara, harbor. this proline...

    v4 x-flow cav plate(s)?

    My 135hp v4 crossflow has what I'm pretty sure is the anti-cav plate as the first plate above the prop. It contains that little curved "fin" for countering torque reaction, I think. Next about two inches above that is another "plate". Don't have any earthly idea what that's for, but I think my...

    premium fuel? '75 135 v4 crossflow

    so far, i've had my "fast little boat" for about a year. it's a stripped down 16 footer with a classic performance hull, [bass boat'ish proportions], and it's powered by a 1975 v4 crossflow, 135hp evinrude. i don't have a single problem with this motor, and i love it! i post about this boat...

    yami 40 2-stroke lower seal-fishing line leak

    one day after having had this motor for about three months and using it a dozen times or so, i finally took the prop off to look at things. it came right off as it should, shaft was still lubed. BUT i found a little bit, 10 feet or so, of light duty fishing line wrapped between the prop and...

    love my big twin!

    rds21b 1959 super seahorse 35hp sure, she has a confounding stumble at idle, but she starts every time, and if she doesn't, it's easy to figure out why. and the stumble smooths out with a little extra power.* today i found out my fancy oil-injected yamaha on my fancy boston whaler, won't...

    seafoam and smoke

    i sort of asked this question in somebody else's thread, and was probably too wordy with it. here's the pared down version: when de-carboning with seafoam as per TD's instructions in the FAQ, does the smoking cease when the carbon is gone? or does it always smoke when you have a lot of seafoam...

    remote controls, salt water care?

    you guys, [like me], who operate in salt water... what do you do at the end of your boating day to your remote box, [throttle and shift cable quadrant, and start key and choke], to keep it protected? after flushing my motor, i usually mist it down with wd40, [i buy it by the gallon a "big...

    strange starter behavior

    evinrude 135hp crossflow v-4, 1975, 135583e, if it matters... the motor starts easily and runs like a champ... at least it does if the starter motor works. seems the starter motor has become intermittent on me. sometimes it works and zings the motor right to life, other times i just get a...

    what to do with old driveshaft? hate to waste...

    just replaced the driveshaft on my '75 evinrude 135hp, v4. the splines on the powerhead end of the driveshaft have over the years, become a beaten down although it still works. i replaced it because i was afraid the splines would eventually give. anyhoo, this driveshaft is otherwise perfectly...
