    Welsh Plug Number

    What information does a Welsh Plug number tell you and where can you look it up. Mine is G3305000 and it's on a 1999 225 Johnson Looper. I'd just like to know what the above number can tell me. I want to buy a manual for the engine and want to make sure it's the right year. Thanks, Duke1

    Big Bore Looper Carb Question

    Guys, I have a 99 Johnson 225 Looper (PXEEN). I was wondering what the difference was between "big bore" carbs and the other was. What carbs should a 225 have on them? Would a set of big bore looper carbs be appropriate for the above motor. I saw a set of stock carbs for a great price...would...

    99 Johnson 225 Engine Wiring

    I just installed a rebuilt 99 Johnson 225 looper on my boat. Engine runs well, but it seems that since the install I've had some electrical issues that weren't there before. I recently heard that OMC made "lousy" engine wiring harnesses during this time and a total re-wire of the motor side...

    List to port during accelertion

    Hello, I've been reading the post on the above topic but still have a question to ask. I put the smart tabs on my boat (24' Grady W/225) and notice that I have a pretty severe list to port when taking off. It will calm down once I trim up the engine and raise the bow. I've got the port plate...

    Tach spiked when T&T used

    Hello, I'm running a 99 225 Johnson, and I took it out for the first time since I swapped my motor from what I had to this current motor. I noticed that just before my tach quit on me all together, it (the needle) would drop down when I would hit the dash mounted T&T switch, then go back to...

    Rectifier Charging Question

    Hello, (99 Johnson 225) I just finished up a problem with my tach not working, and when I tested the R/R, I got that two of the four diodes were open, or giving me the same reading both ways. I figured out that my tach issue was a really a ground issue and once I got that to work, I noticed...

    Tach issue..not grounded

    Hello, I just did a repower from twin 86 140 Johnsons to a single 99 Johnson 225 V6. My mid 80's vintage OMC tacks worked fine on the 140 and now I can't get it to work on the new engine. I figured out that my rectifier was gone, so I replaced it, and my tach still does not work. I used my MM...

    99 225 Johnson O/P Prop Question

    Gents, I'm looking for some information on what size prop I should run on the above engine. I currently have a 14.5X19 SST and a 21x15 I believe in aluminum. I've not had the boat out yet to see my numbers..I was wondering if there was a stock prop I should use as a baseline. The boat is a 85...

    lync & sync question

    Gents, I'm planing on doing the lync & sync on my 99 Johnson 225. I've got the factory manual and I've read it so many times I'm cross eyed. It would appear to be fairly straight forward. So my question is really looking for some reassurance, can a non-mechanic who with some mechanical ability...

    Tach Settings

    Hello, If my OMC tach was set for a V4 engine and I went to a V6 engine, is there anything I need to change on the back as far as settings? (99 Johnson 225 V6) Thanks, D1

    Kill switch question

    Gents, I feel kinda silly asking this question, but here goes. Is there a difference between a magneto based ignition kill switch and a ignition based kill switch? I understand they create the open or closed circuits at different times (one with the switch in and one when it's out) I have a...

    Motor Popping

    Hello, My motor is a 99 Johnson 225 Looper. I've had a ground issue since putting this motor on my boat, but I think I have that figured out ( it was a bad harness). I can start it now but my key switch still does not turn it off, and I now have a soft popping noise when it runs. Any ideas what...

    TOHATSU EXTENSION-Directions

    Hello, I just bought a l/u extension kit..(2006 9.8 4S Tohatsu) got it from the GURU. It got here quick and in good shape...but no directions. Are these things pretty straight forward? Just checking to make sure there isn't any tricks or tips I need before I start. Thanks, D1

    Did I screw this up?

    Gents, I was in the process of doing some work tracking down a possible ignition switch problem (my thread on that is "kill wire question") when I went to start the motor with one of the two blk/yel wires from the PP unpluged. As I was trying to start the engine I heard a buzzing noise, when...

    Kill Wire Question

    Hello, I have a 99 Johnson 225 w/VRO disconnected. I was trying to start it after getting it rigged on the boat, and it wouldn't go. I've got good gas, and good battery, but I wasn't getting spark. I did as the repair book suggested and disconnected the Black/Yellow kill wire in the PP and it...
