Loving the upper trim limit feature on my G2 and wondering if there is a lower trim limit...  I seem to remember seeing something about this.  The reason I'm asking is that even after adding 50 lbs to the bow, I'm still not able to get the bow down as far as I was with my  Mercury Promax.  It is only an issue if I am running at or near bare plane speed which I experimented with more this last weekend.  At 2700-2800 RPM, I'm getting around 5 statue miles per gallon and sometimes a bit over according to my instruments which is great.  She will maintain a pretty stable attitude depending on the sea, but can still be prone to porposing a bit even when trimmed all the way down.  I'm just wondering if there is something I can check to confirm that the engine is trimming all the way to the lowest end of it's range.  Thanks and cheers![thumb]

There is no mechanism which limits trim range limits.  The only configurable variables are setting percentage of lower/upper trim range.

Tilt limit is indeed configurable and will prevent the engine from tilting higher than the limit set.

  Oops, I meant to say TILT limit...

ElderSparky, I don't understand what setting a percentage of lower/upper trim range would mean.  Is there any chance that when I show 0 trim on my gauge and the outboard seems to reach it's lower limit of trim, that an adjustment could get it to trim lower?

Thanks!

Sorry I'll change the word for limit to "position"

I see you were looking for Tilt. But...

As per my post and picture, setting the upper and lower "Trim" position can be done and it is very handy.

I reset mine so I wasn't trimming all the way down each start. I would just trim to the 0% lower position.

Lower position is a 0% reading and upper trim position is 100%. Very cool to have it on the display instead of needing the laptop to set.

This feature is to help with you with your normal boating habits, it does not affect the actual trim operation but just changes what you see on your gauge.

You can also set the max tilt at the outboard by pressing and holding both trim buttons.

Not looking for "TILT".  I mentioned that I love the tilt limit function.  The point of my original post is to ask if there is any way for me to "TRIM" my engine lower.  If you read the original post you will see that I'm looking to get my bow down a bit more at lower speeds.  I just want to make sure I have my engine trimmed down to the absolute lowest position.

Sorry mate, There is nothing to limit or stop it from trimming all the way in. I don't believe they have a pin like the old style transom brackets.

It would be easy to confirm the engine is trimming fully in by just watching when you trim down to make sure the engine comes to it's stop. The negative trim offered by the G2 is the most tuck in offered in the industry if you require more negative trim, wedges and/or trim tab will push the bow of the boat down.

Well I know what it looks and feels like when the engine is at the bottom of it's trim range and reading this statement is interesting.  I've run a good variety of outboards and usually having the engine trimmed all the way down once the boat is on a plane provides too much bow down force and a little positive trim finds a good balance.  On my boat I'm about to add another 25 lbs of ballast to the bow bringing the total to 100 lbs since repowering from a 300 Promax.  I didn't have trouble keeping the bow down with that rig.  So it is kind of surprising to see it said that the "tuck in" on my engine is greater than all others.  Reminder, I don't have trim tabs.  Still considering it while I familiarize myself and educate myself.
