    1991 Honda 40hp Operating Temperature

    I just put a temp gauge on my 1991 40hp by attaching the sensor to the top head bolt closest to the thermostat. My question is what should the operating temp actually be? It's showing me around 190F which I think is high. I previously had an old Evinrude 40hp 2stroke and attached the same gauge...

    2000 Waverunner SUV slipping

    This is a recent acqusition for me. First Jet boat. Every so often it feels like a clutch is slipping. Cavitation I'm told? Is that it? Is the clearance between the prop and the housing too big? It has around 130 hours on it. Any input would be appreciated, thanks.

    Mangled pontoon. Is it fixable?

    So I had my garage collapse under the snow load in the winter on my old pontoon boat. I just got the entire thing apart to investigate the damage. One pontoon is perfect. The other is not. I have included pics. It was a small 16'er, 8' wide. I only had an Evinrude 18hp on it so it's not a...

    Want to rebuild my Hydrocycle

    So I figure it's finely time to rebuild my '68 hydrocycle over the winter. As you can see in the pics it looks like it basically has a top part and a bottom part riveted together. I have never had it in the water but looking at all the silicone along the rivet joint I assume it leaks like a...

    1950's to 1970's 22 cubic inch powerhead swap.

    So who knows the 22 cubic inch engine well? It has a long great history. I recently picked up a 20BA75B which seems to be quite a rare bird. It's a Johnson 20hp from 1975 made in Canada. It appears to be the same as the 25hp engine from that same year other than the fact that the 25 revs at...

    Looking for replacement ideas for old 5.5/7.5 propeller shaft cap

    I'm looking for replacement ideas for a buddy. His prop shaft cap is broken. It is the one that holds the drive pin in on the older 5.5/7.5's, part #303365. It's a soft rubber cap that pops on over the driveshaft. Has anyone created something to replace it? I assume a bolt and double nut would...

    1996 Evinrude Intruder 115hp. Good or Bad?

    I'm asking for a buddy as he's thinking of buying one. It's a fresh water boat. I always work on older engines. This is way to new for me. Any history with this engine? Known issues or just a good ole Evinrude? thx, Steve.

    My buddy is looking at buying a 1999 Evinrude FICHT 115hp. Good, bad or Ugly?

    I work on much older engines and have heard mixed reviews on these newer engines. Any comments, yay or neigh? Thanks. Steve.

    Did Johnson/Evinrude ever make a set of old controls with a key start built in?

    That pretty much says it all. I have several sets of the old dual cable controls but would not like one with a standard old 5 screw ignition switch built in. Do they exist? I've never seen one. Thx.

    Has anyone reattached a Catalina 22 swing keel or permanently mounted it?

    I am considering both options as I have the boat ('77) with the keel currently not attached (pivots rusted off). Lately I have been considering just reattaching it as a shoal keel and permanently mounting it on the bottom horizontally and not swing-able. As I believe it would be easier as my...

    How to tell when you've left the boat in the water too long...

    Well I pushed the season as long as I could, but today after my final spin I had to take my 15012 '53 E15 out of the water before it turned into a block of ice! Sigh... Boating season is over...

    Drive pin hole elongated

    So the drive pin hole is elongated in my '66 Johnson 20hp prop that I just picked up. To the point where it clunks when going into gear and it bust the first shear/drive pin and bent the second one. It is cheaply fixable or time to toss it?

    What year is my 25hp Merc please?

    I know, it's the oldest post in the world. I'm normally on the Johnson/Evinrude side (so please be nice to me!) but have just bought a boat with a Merc 25hp on it. I could find no model #, just a serial number of 0C209688. There were a couple of others numbers cast in the exhaust housing but...
