    Mariner 250

    Gents, Looking to get some feedback from you all about the late 90's Mariner 250 Offshore with EFI. Any major problems? I've found one that appears to be in good shape for a good price. So your thoughts would be appreciated. Thanks, Duke1

    Determining Shift Type

    Hello All, How would I go about determining if I have an electronic shift or a mechanical shifter in my mid 80's 140 Johnsons. I'm inclined to think their mechanical, but I don't know where to look for the information. If they are mechanical like I think, would hypoid 90 be the appropriate lube...

    01 Evinrude 250 HP FICHT RAM

    I just wanted to get a idea what the group knew about the above model of Evinrude. Would this be an OMC or a BRP engine? Did they have the FICHT system figured out by 01? I read that the problem was with the 150 to 175 powerheads and didn't include the 250...is this correct. You can find some...

    Prop diameter

    Gents, I just read the prop article in the FAQ's and I still have a question. I understand that the pitch is the theoretical forward movement of the boat in inches, but what I don't understand is what the importance of the diameter is. Does it have to do with the weight of the prop so it does...

    Starter Solenoid

    I have a 1986 Johnson 140 Looper that I was using the otherday and after a run for about a twenty minutes or so, I found that after I turned it off, it wouldn't start. When I turned the key I got the chirp and the tach zero'd out, but nothing happened....no sound, nothing. I ran back in on the...

    Johnson 140 V4 Commercial Engines?

    How can you tell if you have a "commercial" engine? I saw a post talking about some V4's with V6 gearcases. I also noticed that some V4's have 13 spline shafts and mine has 15 splines. My 140 looper is 1986. If it is a commercial engine whats the difference? Do they have a different WOT than a...

    Johnson 140 Looper VRO prop question

    I've posted this question in the Johnson/Evinrude Troubles side...but this sounds more like the proper place. I have twin 140's (1986 variety) on a 24 Grady-White. I just bought new SST props (14.5 X 19) and I noticed that the left engine (counter-rotating) is easily doing the 6000 rpm WOT while...

    Rev Limiting Screw?

    Does a 1986 V4140 Looper have a rev limiting screw to adjust or is this only done via the power pack which has a 6700 RPM max?

    Johnson 140 5500 WOT MAX?

    I'm running twin Johnson 140 Loopers (1986 year) on my boat. The left motor will easily do the 6000 RPM WOT while the right will only do 5500. I've adjusted the WOT screw and the cable tension with no change. Is there anything else I can do? Should I be satisfied with 5500 WOT or is this lugging...

    Throttle Cable Question

    Hello All, I'm running twin 140 Johnson Loopers on a 24 Grady White. The engines are 86's and counter-rotating. I just put new SST props on them 14 1/2 X 19 and have noticed that the right engine will top out at 5600 RPM while the left will easily do the max 6000 rpm. I have the dual controls on...
