    KB 45 motor mounts

    I am planning on makeing motor mounts for my kb 45. There will be a front and rear clamp style mount with full water cooling on each 1/2 of the clamp.
    From what I have read heat is a bit of and issue with these motors so I came up with a plan to make watercooled mounts....

    I am wondering if there would be an interest in these. I am planning a run of up to 8 mounts.

    I will post pics of a sample mock up hopefully this week

    Anyone interested plz post here...... Thanks Dave

        Pics update. I used brass tubing for the water in and outs.. I can add 90 deg fittings but that will add 16$(aprox) to each mount. They will deffinately make for a neater build. Some dont like them because of the possible slowing of the water flow.


        Your thoughts on the fittings or anything else??? Nice to know before I cut. Dave.

          Beautiful design. However, acrylic is a poor conductor of heat. Aluminum would be much more effective, in my opinion.

            I believe Lonewolf used acrylic because it's a prototype.

            He said...
            "Your thoughts on the fittings or anything else??? Nice to know before I cut"

            That kind of tells me that the real ones won't be made of acrylic.

            Cutting aluminum for a prototype, then a design change, then more cutting, then more changes, can get a bit expensive don't you think?

              They look like a good design
              But I wonder if there is any way to get the front of the motor closer to the floor of the boat
              I have a KB in a 36" hydro and the front edge of the can almost touches the floor to keep the weight lower in the boat (if that matters)

              Just an idea but could the front mount be on the face of the motor somehow with the water pipes going through up and down ????
              There would be more suface area touching the cooling plate and if you already have a cooling can on the motor this might draw more heat out of it from a different surface on the motor

              Just thinking out loud

                Of course you are correct, Diegoboy! I should know better than to post before the morning coffee. My apologies!

                  First off the material is transperant alum . I talk to Scotty from star trek and he transported me some stock to work with......................

                  Ok Now for details. The side pcs of transperant alum are there just to represent the 4 in stringers and would not be included. For and extra charge I am sure I could cut some stringers out od "E" glass for those who dont have stringers.
                  That may or may not fit correctly for each hull.
                  The bottom part of the mounts are mounted to the stringer. the motor s set in place, then the top portion of the mount is screwed down to the lower part.

                  Once the mount is in place the motor can be removed without removing the whole mount , keeping the placemnt the same for reinstallation.

                  HHMMMMMMMMMM, cooling the front of the can. I will give that some thought...
                  Valid Idea. I may be a challenge seeing I am useing a boreing bar to cut holes. A boreing bar does not cut on the bottom, only the diameter.
                  I will give this some serious thought, io like it. Thanks Dave

                    I have looked it over and am thinking about mounting the cooling for the front mount on the front of the can................However 2 things to consider...
                    1 making room for the thrust bearing??? What is the O.D. and thickness???

                    2 will there be room for the coupler and access to the set screws? I plan on useing 3/8 alum.


                    It would be nice to lower the c/g of the motor. specially for a ono the "v " tends to really make an issue for clearance of the water lines.

                    3 Eliminate the lower front water cooling and not have any clearance issues...

                    Response plz
                    Thanks Dave

                      Mount update...
                      I removed the cooling from the front mount and made a seperate cooling plate for the front of the motor. I can now get the front of the motor about 1/4 of an inch from the bottom of my mono..... Tho I will have to make a slight bend in the tubeing for the bottom tubes...

                        That will let you mount the motor lower now

                          Thats why I did this post too get info. It would have made total sense once I set it in my hull and saw how high it was...

                          Thanks Dave

                            Will you put in a good word for me and have some of that transparent aluminum beamed down to me too?
