MX1825 owners – How much do you trim?

Once I go past 1/2 on the trim gauge I start getting prop slippage when turning, are you guys seeing the same?

I have a 150 with 18P Reliance prop.

I cannot tell you how much I have it trimmed up or down when turning. I rarely ever look at my trim gauge. I usually adjust the trim as needed by feel for the boat for what the conditions call for. I know when making sharp turns you have to trim down, but that is pretty common for any boat. If you are making gradual turns I typically don’t have to adjust trim all that much to prevent the prop from slipping. I am running a 200 hpdi.

As a former bassboat owner I understand trimming down for sharper turns, but in the MX being only 1/2 gauge trimmed and feeling the prop slip on average turns seems odd…

For those who look at their gauge, how far are you typically trimmed?

Not a direct comparison as I run the MX-2025 with a 200hpdi. The only time I’ve ever got to 1/2 trim is when I’m trying to see what my top end is. During normal operation, 1/4 trim would generally be about as high as I ever have to go.

I run the same – MX1825, 150, same prop. I only trim up above about 3800 RPM. At that time, depending on load, I would trim up very gradually to around 3/4 trim at 5500 or more RPM, which I almost never run. My experience is that the 1825 needs to be trimmed down all the way most of the time to avoid prop slip on turns and bow porpoise.

thanks, I appreciate the responses

What prop are you running?

Opps, over looked that. That is a good prop for that boat. What speeds are you running when you have those issues? Half throttle, wot? How sharp of turns are you taking?

I would say 3/4 throttle or less, I would not consider the turns I was taking as very sharp at all…about what you would do when turning around a shallow point… I started this thread because I thought it was unusually low trim height to start seeing prop slippage…

I have had mine to 3/4 trim on wot straight ahead. Slight turns just under 1/2 trim. Sharp turns way back down on the trim maybe an 1/8.

I would say thats about normal from what I have seen. Might be a little more slippage because of the 18p compared to the 19 but that about normal.
