Boat has Baby / Typhoon Outboard Information

[Russell Rau]

Just to keep the CD World informed of the latest, I wanted you to know that my CD=30 Cutter gave birth to a wonderful Typhoon this weekend. Mom and baby are sitting right next to each other and it is very interesting just to stand there and compare the lines on the two boats. Now I need to know all I can about this wonderful new addition to our family. Specifically, I have a Nissan 5hp long shaft (I believe) that I installed on the Spartan motor mount and the set up works well if two people stay on top the stern. What solutions have been discovered. One person said to use an adjustable outboard motor mount attached to the Spartan bracket, but this would seem to detract from the cool look of the Spartan bracket. Any advise would be greatly appreciated. Thanks.

If you need two people at the stern it must not be a long shaft. I must sit as far aft as possible to achieve good forward thrust. I use a tanaka 3.5 h.p @24 LBs. I also lowered the position of the motor on the bracket by 2 inchs. if someone goes forward while motoring the prop is out of the water. This winter I will modify my outboard with a longer shaft this is possible because of the unique configuration.

The tanaka 3.5 h.p has a 17" length.. My Tohatsu has a 20" length. I wish it were 25".
The Tohatsu cavatation plate is just barely in the water at rest, and up to 5" at half power with a passanger or two.
I also lowered the position of the motor on the bracket by 1.75" .

The real issue for me is the cavatation plate depth at slow speed. When I'm using the outboard I'm usually near other vessels, and if we get a small chop I sometimes lose manueverability.

When we got our Typhoon nearly 20 years ago (which never had a motor) we had a piece of bronze welded to the motor mount to lower motor about 3 or 4 inches. This put the cavitation plate just below the water. Works fine, but we still need someone at the helm if anyone goes forward.

Russell:

Congratulations on your new addition. If Roger at Bristol Bronze does not have a solution, we could make up a new mounting plate or a pair of offset brackets that would lower the mounting surface a few inches. Let me know if you are interested, and how much of a drop you need.

Maybe the little Ty will grow up to be a 40!
Hope this info on the best bracket arrangement isn't too late.
The solution I found to the "short-shaft" problem was the retractable s.s. outboard bracket, Model # 71038, sold by West Marine as part # 20461. (Also avail thru M & E Marine, 1715 Mt. Ephriam Ave., PO Box 601, Camden, NJ 08101)
I mounted it on the starboard transom (favors a starboard tack which the heavier bronze mount does not). When I'm solo, if I go forward (and I'm 220#) and stay on the starboard side, my shortshaft, 1974 Johnson 4hp will not cavitate until I'm on the bow and then it's only gurgling but not out of the water.
This highly-adjustable bracket that can compensate for the transom angle, and in conjunction with motor tilt, you end up with the drive shaft near perpendicular (ideal) to the water's surface. You will then gain about a foot of veticle travel. When fully retracted and engine is tilted forward, even on a port tack, it is completely clear of water.
On the down side, bracket costs about $135.00, but it comes with all hardware. You'll have to manufacture and install a thin s.s. back plate (about 6" x 12") to attach on the inside of the transom to more evenly distribute the load. It costs about $15; drill the holes a little oversize for easy mounting.
I'm sixty-years old and did it myself so it can't be that difficult! I could have afforded to lose some weight because slipping into the quarter berth backwards with your arms over your head trying to work 'blind' is a study in claustrophbia, but I did it.
It makes for a really nice, neat, low-profile, light-weight bracket that I'm throughly satisfied with.
Hope this helps in parenting the new addition to your family.
