The one that was messing me up was the little filter in the fuel pressure regulator. Besides that one I change all other filters yearly unless I have a problem. I am running the regular black fuel...

With the 29 I am turning 5500 at 75 witha little throttle and alot of trim left before the boat get too wild. I am currently looking for someone with the same boat as mine(190 fs Randall craft) to...

I will check that. Do you have a picture of the intake that shows which port? Right now it is on the one all the way at the top. I need to breakdown and get a service manual for it. I have merc...

I talked to Eric yesterday. He told me these were good engines. As for the mid. I am 99% sure it is a Optimax tuner. When I got it it was still set up for an opti. I had to change the fittings that...

What was the cause to make these early opti engines to blow up. I have a 225 efi now and am thinking about putting an optimax powerhead on my midsection. (it is an opti mid). I like my efi but the...

Can Eric Simon program a 225 computer to a 250 like he can with the efi computers. What would I have to change to make a 225 a 250

I have a 225 3 liter merc that I converted to efi. I read about the efi's using ql77cc plugs. What about mine that was converted to efi from carb. Should I use the same plug or stay with the ones I...
