You guys are making me very depressed. I just ordered the 2008 6HP Nissan OB engine for my Morgan 25 which weighs 5,000 pounds. The Nissan dealer says the only options for the prop is 7, 8 or 9 inch and the engine comes with the 8 inch prop.
Some questions for Audeojude: What year engine did you test? A 6" pitch prop is not offered on the new engines. I'm currently using a 3.5 HP Nissan 2 cycle outboard and it pushes the boat at 5 knots with no winds blowing. Where can I buy a smaller pitch prop? Are you sure your instrunents are calibrated properly? I might still be able to exchange the OB for the 8HP model but don't want the extra weight and I also wanted the extra long shaft.
Please respond ASAP
