LH Sportmaster on a Single Outboard Boat

[Tango]

Has anyone here run a LH SPortmaster on a Single Outboard boat? I am getting down to the final stages of building my Eliminator for the Parker and thinking of switching to a LH Sporty to take advantage of the big left hand turns on the course. Considering how rough the water is going to be, my thinking is that I could get into the power harder/sooner out of the turns.

Thoughts?

I did on a 21 obsession (21daytona). No problems at all. I didn't race in circles, so I can't comment on that.

You'll have to dig in the rules, but I think they are not allowed...and the counter shaft due to design has a built in fracture point.

2. LOWER UNITS:
a. Green lower units must remain as delivered from the manufacturer & shall run the propeller shaft no higher than ½” below the last 3’ of the running surface. The prop shaft must be parallel to the running surface at the time of measurement.
b. Non green lower units may be modified but must be a V6/8 style. No XR6 style units allowed. Shaft height limited to 1” below the last 3’ of the running surface.
c. All lower units must have a working forward, neutral, & reverse from the driver’s seat.


Not excluded but please explain a "built-in fracture point" if you will.

What? Elaborate please

I've been running LH lowers for almost 4 decades. Alone and in twin and triple apps. They don't fail any sooner....

I agree..... seen Lh lowers go bad...the halve thing gets out of that grove and bad things happen. All lowers break.....the only safe thing is the prop nut.
