DF150 is it a 20" or 25" shaft?

[transcat]

I'm looking a purchasing a used 2006 Suzuki DF150 from a guy who lives about 5 hours away. The problem is I need a 20" shaft for my boat and he is not certain if his is a 20" or 25". The motor is on a Larson 186 ski boat and by the looks of it I'm pretty sure its a 20". I have the all the numbers on the ID plate but I can't find anything on the plate that tells me anything. Is there something I can tell him to check or measure? Thanks for the help.

there os a couple of things he can do, simply measure from where the motor sits on the transon, to the cav plate, it will be approx 20 or 25", 5' is a fair difference. The model number will also tell you.
