    Fiberglassing Technique Video

    I've been meaning to make a video about the fiberglassing technique that I use. Since I am doing quite a bit of fiberglassing right now, I made the video. . I hope it is helpful to those taking on a fiberglass project.

    I/O (Sterndrive) Conversion to Outboards

    In the 'better late than never' catagory . . . . Maybe I'll pick up a few pointers . . . or find out if I am making a blunder. :ROFLMAO:

    Alpha 1 Gen 2 - leak & transom service questions

    As for the trim pump hoses . . . make sure it is not the y-pipe gasket leaking instead of the trim pump hoses.

    Jeez! What happened to global warming

    The reason it has been so cold lately in the northern parts is not about global warming or anything like that. It is because this year I am fiberglassing my extension pod in the garage, which barely has any heat.:LOL: Once I'm done with the fiberglass, I'm sure it will warm up. :ROFLMAO:

    Survey

    Good luck with the survey and mechanical inspection. If you have not chosen a surveyor, you can find lists of certified surveyors on the SAMS or NAMS websites. I often Google their name/company as you may find various forum posts that can serve as references on their work. Not sure if you had...

    Survey

    Also keep in mind that many of the newer bearings (u-joint & gimbal) are the non-grease-able type. Yet another surprise I got when I did my annual maintenance the first year of ownership.

    I/O (Sterndrive) Conversion to Outboards

    To the extent that I have researched, OB's of all sizes are open cooling (no HX). . The main advantage with OB's is that you can/should tilt them up out of the water when not in use. This alleviates the issues of galvanic corrosion and marine life growth. Since the lower unit and propeller...

    Survey

    I had a couple years of service records from the seller on my boat, which was helpful. A bad bearing you can usually hear on a sea trial. My surprise was after the first year of ownership, the engines (alignment) needed quite a bit of adjustment.

    Survey

    It would be a nice idea, but you may get some push-back. Also increase your estimated cost to about $2500 if the drives come off (for inspection of the alignment, gimbal and u-joint bearings).

    Survey

    Also, keep in mind that some of the things your are looking to get may not be in the realm of a mechanic, unless the seller agrees. U-joints, Gimbal, and alignment would require the drives to come off, and it may be beyond the normal extent of inspection.

    Survey

    Typically it is a Marine Surveyor (structural & fittings) and a certified 'mechanic'. Try to find a surveyor who has a mechanic that they typically work with. Sometimes you will find a surveyor who is also a mechanic. Expect to spend about $1,500 in total perhaps a bit more. Sometimes the...

    I/O (Sterndrive) Conversion to Outboards

    I will keep the trim tabs, even though I don't use them much. Speaking of which, I unfastened the trim tabs the other day, just to gain some clearance. There was a stainless steel plate between the trim tab's mounting plate and the transom. It was stuck on with what appeared to be 5200. I...

    I/O (Sterndrive) Conversion to Outboards

    Depends on the crew that we have aboard. Often the water temperature rises a couple of degrees by the time we leave. :ROFLMAO:

    I/O (Sterndrive) Conversion to Outboards

    For those following along, here is the calculation for change in CG . . . I previously did a similar calculation for the fore/aft movement of CG. 12in x 1400lbs + 19in x 2250lbs - 12in x 400lbs = 54750 in-lbs = ? in x (11000-2250+1400+400) lbs 54750 in-lbs/10550 lbs = ? ? = 5.2 inches

    I/O (Sterndrive) Conversion to Outboards

    I get over to THT once in a while. There are a few conversion threads over there. Not sure I'd want to do any marine consulting . . . kind of late in life to become a Naval Architect. It is true (as far as I can tell) that the OB versions of the typical sterndrive boats use the same/similar...

    I/O (Sterndrive) Conversion to Outboards

    However, at the end of the day the CG would be back to the higher point. :ROFLMAO:

    I/O (Sterndrive) Conversion to Outboards

    Very technical . . . Here is what I Googled . . . "A wee bit" means a very small amount, degree, or quantity, using the Scottish word "wee" (meaning small or little) with "bit". It's an informal phrase used to say "a little bit,"

    I/O (Sterndrive) Conversion to Outboards

    I did the 'vertical' calculations and it looks like the CoG (Center of Gravity) will move upward about 5.2" (0.45Ft). The fact that the boat is a 10'-10" (130") beam will probably suffice for lateral stability. I may notice a slight bit (wee bit :LOL: ) more tenderness, but I'm thinking it...
