Sounds like many of us are looking forward to the warm days to come and what boating adventures will bring. The first link is a video of one of the most memorable days from 2016. A pod of 30+ Orcas…Continue
I have my boat out of the water and found I need to replace my wheels. The boat originally had 18 X 20, 3-blade wheels giving me a lot of prop slip and issues with the aft wanting to swing forward when the vessel plowed into 6' or higher waves. I put 18 X 18 4-blade wheels and significantly reduced prop slip and was able to plow through waves without the aft end swinging around in heavy seas. With 18 X 20 3-blade wheels the new Blue Water Mercruiser 5.7 Liter inboards reached 4200 RPM max and 4350 RPM max with the 4-blade 18 X 18 wheels. I measured the shaft distance to the bottom of my hull and found I have 11.75 inches of clearance. This means I can put 19 X19 3-blade wheels on the boat. I plan to run some simulations to see which wheels give me the best range for my boating requirements. I am having a new fiberglass tank installed which will hold more fuel so I need to re-enter my fuel weight parameters before I can make my decision. I hope to know the tank volume later this week.
As far as your boat; I would be willing to run your parameters to see what the program recommends but you should also give the same info you give me to your wheel salesman to confirm / recommend wheels for your vessel. Let me know if I can help. I won't charge you anything to run the simulation. It would be helpful if I do run your boat through the system, to get your water speed versus RPM results for various RPM's with your current configuration and after you put on new wheels. The program has a lot of graphs that will show what improvements are realized and what your range/fuels cost will be at various RPM's and loads.
