I have a 92 Spirit 17 with a Yamaha 115 4 stroke and do not have any issues with performance. I too do not have trim tabs on my boat. The Spirit handles the 4 stroke just fine at any speed. Any boat will porpoise if you don't trim right.
Got a 92 Spirit thats lost a bit of her shine. Light to medium oxidation. Boats been wharehouse kept, but after 21 yrs needs some attention. Any ideas on products or success stories?
What year did Grady begin and end production of the 175 Spirit Center Console? I just found a 92 in great shape locked up in a warehouse and was curious.
