    I/O (Sterndrive) Conversion to Outboards

    This has been covered along the way . . . the transom gets additional support bracketing, much like the factory does on their outboard versions.

    I/O (Sterndrive) Conversion to Outboards

    Not extending the strakes (if that what you are asking) The extension will have a somewhat mild chine (as shown). I might give a little bit of 'lift', but not sure.

    I/O (Sterndrive) Conversion to Outboards

    It's a good thing that I was paying attention in Geometry class (way back when) 🤓. Figuring out the shape & dimensions of the outer supports has been a bit challenging, but I think I got it now.:unsure: . I'll have to make an adjusting cut in the center support to match the outer supports. (I...

    I/O (Sterndrive) Conversion to Outboards

    I moved things to a more sunny location in the yard . . . I think the sun will be enough to cure the resin. I installed the main (center) support. This piece I am glassing in - just so it stays put during assembly of all the other pieces. .

    I/O (Sterndrive) Conversion to Outboards

    I got out there early this AM to check the glass/resin. It cured OK. Here is a pic of the 4 pieces of the contact area set in place and glassed at the edges/corners. . I used some cardboard on the transom as a 'spacer' to mimic the fiberglass thickness, then stuck the Coosa pieces to the...

    Have a live mouse inside a interior wall. No insulation.

    This is what I use . . . . Along with some lock-able bait traps. You should find out where the probable points of entry are and place the traps near the line of travel.

    I/O (Sterndrive) Conversion to Outboards

    My preference is to start cold and add heat once the glass is laid up. I’m thinking if the resin were to start warm, it would tend to kick too fast and cooling it down would be too late. I’m using VE resin, so it’s open time is a bit longer than poly resin.

    I/O (Sterndrive) Conversion to Outboards

    In other news . . . I have the 4 'transom mating' pieces secured to the transom with a about a 3/32" 'spacer' all around to mimic the fiberglass thickness. (Pics to follow in the AM.) Temperatures barely hit 60˚F today . . . more like 57˚F. I am having to tent the work area after the glass...

    I/O (Sterndrive) Conversion to Outboards

    Yup, it was one of those things . . . asked myself should I cut out one more piece and call it a day . . . Doh 😖

    I/O (Sterndrive) Conversion to Outboards

    Some how, I managed to cut one of the pieces wrong. So, I got to practice glassing the Coosa board. . . All set . . . don't do it again 🤪

    I/O (Sterndrive) Conversion to Outboards

    Progress Update . . . Lots of measuring and cutting today. I'm into 3 of the Coosa panels . . . Here is what I've cut out so far (highlighted in orange). . . The big top piece (upper right in the picture) took a while to get just right. The other pieces were not too bad . . . lots of...

    Alpha 1 Gen 2 - leak & transom service questions

    I'd be finding the leak first as it may impact the rest of your planned work. I would think you could run the engine on the 'muffs' to determine if the engine is leaking. Keep in mind that when the boat is in the water, the exhaust bellows is full of water as is the lower portion of the...

    Impeller replacement glycerin and grease

    Both Volvo and Mercruiser call for their own grease, and it seems each call-out is a different type of grease. :rolleyes: I have used a single marine grease for everything with no adverse effect. On impeller case internals if often use dish soap for the initial break-in.

    I/O (Sterndrive) Conversion to Outboards

    Yes . . . lots of bolts. The 'glue' is more of a water-tight sealant. . . :LOL:

    I/O (Sterndrive) Conversion to Outboards

    Sunday was a fun day . . . Patriots football . . . narrowly escaping defeat 🤪 We get there fairly ealry and have the pick of the tailgating spaces . . . . . . Today is back to business, but the weather might have its input on how much gets done . . . . I got some detailed dimensions and...

    I/O (Sterndrive) Conversion to Outboards

    It gets worse . . . Would you sell just the engines? (no . . . they don't work without the controls and wiring) I'm a Merc Tech, I know this stuff . . . (no you don't) How many hours? What year? (the listing has all the info) I just need the throttles . . . how much for those? (same price as...

    I/O (Sterndrive) Conversion to Outboards

    Weekend Update . . . A belated Happy Halloween to those who partake in the festivities. I will be back at the outboard conversion over the next few days. Some fiberglass supplies arrived yesterday and more stuff is arriving today. I've been cleaning up the engines, outdrives, and other...

    I/O (Sterndrive) Conversion to Outboards

    Having the transom scooted out the 20" from the bunks is actually helpful in verifying some of the measurements. I got one of those digital protractor thingys so I could measure the various angles. . The transom is 12˚, which I sort of knew from the drawings I got. Mercury recommends a 14˚...
