    After 3 years ! clicking noise when turning - shuts down at full throttle.

    Finally got it in the water yesterday. 4 ft seas greeted us. Lots of fun. If it wasn't for you guys it wouldn't have been possible.(no not the waves just being there !) Many thanks. Only two issues left maybe these will be easier than the last ones. 1. After running for about 2 hours pulled...

    cutout switch vs throttle - overview ?

    I am trying to understand the throttle - shift - cutout switch relationships. I don't see how it could work which doesn't help much. If this is posted somewhere please let me know where.

Went to adjust the shift /throttle cables and found that the throttle on the carb is full closed when the throttle lever is either full forward or full back. The only time the carb is full open is when the...

    Wish it would just click already - Alpha 1 bellows install

    I just installed the drive shaft bellows on my Alpha 1 and did not get the click of the seal entering the grove. The areas where the bellows attaches to are pretty beat up (it is an 84 unit) and with the glue gelling real fast it was almost impossible to maneuver after a few minutes. I think it...

    I purchased a new cooling hose that goes in the gimbal housing to bellhousing. This is an open system if that matters. I read somewhere that this hose needs to be trimmed back to 13inches prior to installation. If it isn't trimmed it will kink. In another thread someone said that they did...
