Hey guys, the forum is great, I've learned alot already. I've read alot of other posts, but none seems to fit my situation exactly.<br /><br />I'm having a problem with an 89 Searay (Mariner?) 135 HP V6. Just bought it, ran great. After a couple of trips, all of the sudden, it just didn't have any holeshot, (wouldn't pull me up on a slalom ski, with only 2 men in the boat) and would only pull about 4500 rpm WOT.<br /><br />Took it to reputable outboard guy, who said it was probably bad gas. Compression is approx. 135 on all holes. I filled it full of 92 and it ran like a champ on the next outing. With 1000 lbs of people and a full gas tank, it yanked me right out of the water on a slalom ski, (I'm about 225 lbs).<br /><br />So, I carefully filled the tank full on the way home from the lake, thinking I must've taken on water condensation from not having the tank full before. Next trip out, the same problem showed up, it would barely pull me up on two skis. I have to admit, there is a noticable smell of gas, so it could be loading up or something. But I guess I just figured that would "clean up" after running at the "crippled" WOT rpm of 4500 rpm for a few minutes. Plugs all seemed reasonable.<br />Battery is at about 12.58V when engine is off, and 13.5 V when the engine is at 2000 rpm.<br />Inductive timing light indicates "fire" to each plug wire, (assuming that I'm not getting erroneous "crossover" from a nearby plug wire that would falsely trigger the timing light's input).<br /><br />I've read alot of posts from this forum that indicate many possible sources of this problem: bad gas, water in gas, stuck float, bad fuel pump diaphram, bad coil, bad power pack(s), bias of power packs not equal, stator, voltage regulator, and rectifier. I guess I'm overwhelmed and wondered if there was a most likely candidate considering the year and model of this motor?<br /><br />Any help is greatly appreciated,<br /><br />Thanks,

JB,<br /><br />You are right. I must've accidentally <br />selected the forum below the "mercury & mariner outboard" forum. I will post again on the <br />correct forum.<br /><br />About the motor, as far as I can tell, <br />it is a 1989 Mercury/Mariner 135 HP,<br />original equip. on a 19ft. Sea Ray, 19P prop,<br />motor #C213481<br /><br />Thanks for your help.
