"Our company has 2 31 Ocean Pro Parasail Boats that in the last 2 years were repowered with Yanmar diesel 6LPA-STZP2 315 hp motors. We run Mercruiser bravo 2 outdrives with a 19 inch prop, and the problem we experience is a tremendous turbo lag when we go power up for take offs and landings. The lag is not bad when the parachute is not in the air, but there is much more resistance on the motor when it is in the air. We had 21 in props on the boats, and then went to the 19 in, and the problem got better but is still unacceptable for our purposes. Any ideas on what might help us with these motors? Thanks for your help!!!"
