Re: 2010 215xi Smart Tab sx10512-90 installed PICS
WOW, I have to ask, did you even read what nauticus tabs do before you bought them? Why did you buy these tabs in the first place? The reason I ask is, these tabs automatically (when adjusted correctly to the right position for your boat/weight) will put your boat in a much better planing and running attitude than it ever was from the factory all the time. I will try and explain, but you should read this - http://www.nauticusinc.com/pdf/nauticus_smart_tabs_tech_info.pdf
Running trim down should not cause vibration or hurt any drivetrain. 90 degrees to the waters surface is 99 percent of the time, the most efficient place for your prop to be. It is where you get the most bang for your buck! It is where you receive the most thrust per rpm! After you are on a plane, yes, you can trim up a little to gain speed by reducing friction to the water.
These tabs should not be causing an unsafe boat attitude, (Bow Down) so much that it is unsafe. If they are, you have them set up wrong with to much pressure from the actuators. These are valved, so once on a plane they relax, this is why you can still use your motor some to adjust bow entry. You are not correct when you say having the motor tucked in in rough seas is dangerous, exact opposite! Having the motor tucked in gives you the most control of your vessel because it is where you get the most thrust! When boating in a rough head sea, you want your bow at the proper angle as to cut throug the waves, not pound against them, usually this is bow down, with trim tabs down. Following seas can be a complete different story, you want trim tabs up all the way!
I'm telling you, you have set up these tabs wrong and I am sure nauticus will be more than happy to point that out if you take it to them. You are the first person I have ever heard of having issues with porpoising after the install. Have you told nauticus how you use the trim? Half way trimmed is usually almost out of the water.
