What shaft length do I need for a lower unit on a 2007 Merc 250 ProXS on a Champion 202 Bass&Bay? It has a Torque Master now.

Thanks in advance!

Measure the center section for shaft length or better yet to measure the torque masters shaft.

Thanks guys! Measured mid-section today at 15" will head down to the shop on Monday to measure shaft.

On another note I posted in a different thread about my boat (Champ 202 B&B) kicking sideways above 50 mph. I guess the issue was the lower unit as yesterday it grenaded on me. Gear fragments punched a hole in the side of the case so its toast. Expensive way to learn a lesson but there were no other indications that the lower was fixing to go sideways other than that occasional weird sideways kick as I cruised along. Of course hitting a log/stump right before didn't help. Wonder if insurance will pay? Otherwise I got to swallow this one.

Depends on your insurance adjuster. Just having a hole in the side of your gearcase won't get it, but a big dent in the front of it usually will.

Wood, especially water logged wood won't leave much of a mark. It did however kill the engine. Which to me indicates a substantial strike. Now all I have to do is convince the adjuster. Thanks Pat, yon've been a great help over the years.

ANY sort of hull damage will greatly increase your argument with an insurance minion.

BTW, the shaft measured 20", go figure!
