I know this may sound dumb but is there a difference between trim tab pumps and outdrive trim pumps???????

Yes.

I assume we are talking about k-planes?? If so, what is the difference? Mine look the same.

They have different flow rates.You can use them, if you reverse the hoses, but the tabs will move very quickly. I know, that is what I did and they work fine, just need to bump the tab rocker switch to adjust trim.

the 4 on my cig are the same.

Cool. Thanks guys. And yes I am talking about K-planes. The hunt for pumps is on.......

The four on my Formula all appear to be the same.

Thanks Joe. Shoot me your address when you get a chance. I will send you those gauge panels when I get them cleaned up.

Thanks

I found the old transom plate and it has the thru hull fittings. The new plate from Mercury does not come with them. How soon are you planning to install ?
