Please explain
I am new to my 312 fastech. Wondering what i am doing wrong? This has happen twice already, when taking off normal I notice or it feels like the boat will roll over. Both times I come off throttle and and it then corrects itself, then I proceed to take off again and it is fine. Are drives too high? Should the tabs be down on take off etc? Will these boats roll over? Again this is normal take off. thanks |
I haven't had that happen, but I have noticed that the 12" x 12" trim tabs are useless!
Looking into putting bigger tabs on... |
I’m running the 280 K plates |
They have to be better!
|
Drives tucked in and tabs level or lower
|
What does roll over mean? Flip backwards?? Roll over to port/starboard?
|
LOL..............^^^^^.....next time leave the tabs neutral and just use the drive trim, you may have one drive trimming up and the other staying tucked, are there two separate switches for the drive trim or a single on the throttle ?
|
Yes roll over port to starboard. Yes two separate switch and one on the throttle to control both at the same time. Also going to adjust tabs and drives to be even with hull at around 5/6 on trim indicator or shouldn’t it be set to some other number. is that what you mean ? |
Which way are your props spinning?

and will add make sure one of the drives does not bleed down and or both are equal when you trim at the same time for either direction and for the tabs as well. |

When I ran that boat, I swapped the 32 Pitch 4 blades. to spin out, it made the boat much more stable and picked up speed. I would make sure they are still spinning out. the boat will handle and ride much better.

Sounds Like Work...

My understanding is that Formula turns all their FASTechs out for stability, docking etc. If this boat is turned in I would think it was changed for the sake of gaining speed. The resulting instability may well be what SYDWAYZ said where maybe some more tab could help this out. Otherwise I would turn them out and expect a correction.
Mine are out and I'm glad of it at the dock even if I loose some speed. My TRS were bad at the dock so these outspin B1's are a blessing for control. |
Put drives all the way in, shouldn't need tabs unless shallow. Do you have indicators and do they work properly?
My 353 is very sensitive to tabs, I try not to use them unless in quartering seas. Use the drives to set the attitude. The drives doen't always go up and down at the same speed, if using the throttle contol it may lift one at a different speed than the other - I choose not to use it for that reason. I like it to drop the drives for a big wake, otherwise its a crap shoot especiall if you don't have indicators. |
