2007 F155 TLR Propeller

[conchyjoe]

I have an aluminum propeller for a 2007 F115. It does not have the spacer between the lower unit and the propeller. The existing prop fits and there are no adverse effects from running the old prop. Do I need the spacer (63P-45987-00-00) if I buy a new stainless prop? I am interested in the 13.25x18 performance series (MAR-GYT3B-V4-18) based on the performance bulletin for a Sea Hunt Ultra 186. I just bought the boat and dont know how it was originally configured, hence the question about the spacer.

Yes the rear spacer needs to be on it.
