    Trim Up or Down for best hole shot with skier?

    I'm new to owning skis (have done it many times myself) and have a 16ft aluminum boat and old 35hp motor. I can get tubes on plane but am having trouble getting skiers up. I know that the boat is too heavy and the motor too small for the application, but wanted to see if changing the trim would...

    No Trim Tab?? What do you adjust on '79 Evinrude 35hp?

    I have a 1979 Evinrude 35hp motor that runs great. The only minor problem is that the boat always wants to turn to the right, which tires out my arm on the tiller! At fishing opener this year I experimented with moving the motor along the transom but that didn't seem to help. The skeg seems to...

    Can't fit wrench around spark plugs! 1979 Evinrude 35hp

    I've had a great 1979 Evinrude 35hp motor for the past few years. It's top notch except for one problem. I can't get any tool that I own to fit around the spark plugs. None of my spark plug sockets fit and I can't get a regular wrench or pliers around them. The problem is that the plugs are...

    Emptying the bilge - a worthy read

    I just finished reading the sticky for beginners and thought that there was one important piece missing from the article: clearing out the bilge. Most states have water infested with some sort of foreign plant or marine life (Eurasian milfoil, zebra mussels, etc. up here). When I'm at the boat...

    Adding gas tank to 16' Fisher

    I want to put an after market below-deck gas tank into my boat. I'm thinking about carving out some of the float foam in the rear and nestling the tank in there. Can anyone think of a reason that I shouldn't do this, beyond my boat being less bouyant if I take on water? Are there any pitfalls...

    '79 Evinrude 35hp: backfires since rebuild

    During fishing opener this spring, my 1979 Evinrude 35hp overheated and blew the gasket. The shop fixed it for me and said that there was no apparent cylinder damage. I got it back and struggled to get it running. It finally started and kept running. After putting along for 1/4 mile I hit the...

    '79 Evinrude 35hp - No pee stream...muffs?

    I fired up my 1979 Evinrude 35hp motor last night. It was the first run of the season. I had the hose running and the muffs on the water intake along the shaft. The motor fired up and seemed to run well. However, no pee stream came out of the back...or anywhere. I ran it about a minute to ensure...

    Minnkota control panel shot? Is that right?

    My Minnkota Powerdrive 40 is about two years old. Last fall it started working intermittantly. I pulled the foot pedal apart but it was clean as a whistle, no corrosion. I just took it to a Minnkota service center. The guy tested the pedal and said that it was fine. Without even looking at the...

    What's under the Deck?

    I've got an '85 Fisher that a 16.5' v-hull fishing boat. I would really love to put a permanant fuel tank under the metal deck. Short of just cutting away to see what is under there (i.e. structural supports, mice, etc), is there any way to know if I could mount a under-deck tank under the front...

    '79 Evinrude 35hp - Cylinder not firing...kill switch?

    My bottom cylinder works most of the time, but occasionally decides not to work. This sounds like a loose/bad connection. I'm still trying to track it down but have heard that it could be the connection from my kill switch. Has anyone heard of problems with the kill switch cutting power to only...

    Carbs on a '79 Evinrude

    My '79 Evinrude 35hp shop manual says nothing about spraying fogging solution into the carburetor throat while running. I've done this with all of my other old motors (this is the first time that I've winterized this motor). I also couldn't find the carburetor throat. Do I not need to do this?

    Clymer or Seloc manual?

    Alright, I'm going to buy a repair manual for my '79 Evinrude. I noticed that Clymer and Seloc both have manuals. Let's hear your preferences for which is better...or pros and cons for both.

    '79 Evinrude 35hp - Lost cylinder again...help!

    Back in July, my '79 Evinrude 35hp lost a cylinder. I replaced both coils and eventually fixed the problem by installing a new power pack. It ran great for several outings until this weekend. I was putting along slowly when one of the cylinders stopped working again. However, later that night...

    '79 Evinrude 35hp - No spark in bottom cylinder

    Only the top cylinder is running. I know this because I replaced both plugs and the bottom one is still spotless after running the motor. Also, if you remove the plug boot while the motor is running there is no change. I bought and installed a new ignition coil, but that didn't solve the...

    Fisher blueprints - - Need to know if I can add below-deck storage/gas tanks

    I've got a mid-80's Fisher boat (16.5' V-hull). I want to install an internal gas tank and possibly a below-deck storage bin.<br /><br />Without ripping up the floor, is there any way to determine what is below? I'd want to verify depth, vertical, and horizontal space available to me.<br /><br...

    '72 Evinrude 25hp -- water backsplashes and sprays

    I've got a 16' Fisher boat with my 25hp Evinrude. When boating around at WOT, a tremendous amount of water splashes up from around the motor shaft and either straight up or against the boat.<br /><br />I shimmed the motor, adding about an inch of wood underneath the mount to raise the entire...

    72 Evinrude 25hp WOT and prop selection

    I've got a 1972 Evinrude Sportster at a stated 25hp. From what I understand, these motors are really 18hp and it feels like even less. My prop is pretty chewed up so I think a new one would make a difference.<br /><br />What is the recommended WOT for my motor? I don't have a tach and no...

    How can I increase HP on a 72 Evinrude 25HP?

    I took my '72 Evinrude into the shop a few weeks ago for winter maintenance. I told the guy that it doesn't seem to get the same power as buddy's with similar boats and 25HP outboards. He said that the 25HP Evinrudes from this era were really more like an 18HP motor.<br /><br />Is there a way to...
