Picked up a 9.9 mariner, having some questions for you mercury guru's. Serial number is 682cl 552937. I think it is a 1980, but, trying to find a prop for it , you have to put in a serial number. Won't take the number I have. Am I missing something? Thanks for your help.
I have a 73 rude 59 hp. Model 50373r. I have cleaned and rebuilt the carbs, but, I can't get it to idle. Seems to be dumping gas untill it floods out. I have tried everything, checked the float drop twice, adjusted numerous times. Lower carb is especially bad. Beginning to wonder if these carbs...
Friend brought me this engine to get running. Sat since 1982. It's got the quicksilver LU. Got it going, then put new points, condenser, wires, impeller, rebuilt carbs and fuel pump. Compression was 120 on all cylinders. Now it runs for a while , then quits.Today after going over everything I...
Not sure if this is where to ask this, but, I have a 1980 150 hp Johnnie on the back of a 1985 Hydra Sport x270. Blew a 140, and replaced it with the 150. Now I have a porpoising problem. I'm thinking I have the engine to low. I used the same holes, on the mount as the 140. I did notice the skeg...
I have a 1980 Johnson 150 (j150tlcsr). My base gasket was leaking, which I replaced this year. Now it's leaking again. I read somewhere, on this forum, that BRP has an upgraded gasket (metal backed). I am looking for that part number. I'm positive I installed it right, torque properly and all...
I just bought a Turning Point aluminum prop (LE1423) for my Johnson 150. 4th time out, I noticed dime sized spots in the middle of each blade. After calling TP tech line, I was told it was cavitation burn. The skeg has taken a pretty good hit (previous owner) and I cleaned it up, best I could...
I'm "fixing up" an Elto Pal, took apart the LU to find nothing in it. It says "grease" on it, was wondering if it just takes grease or is it something special like lubriplate 100. Thanks in advance, fishdady
Bought a 1980, Johnson 150. engine runs great, but, after 34 years, cosmetically, looks bad. I want to paint it, but, researching it some say use etching primer, some say zinc chromate. Anyone have any thoughts. Thanks in advance, Fishdady (Chuck)
I have a '78 70hp Johnson. I have a gray wire coming from the remote control box. I tracked it down, on the wiring diagram and it runs to the rectifier. Question, I am assuming this is the tach wire, am I assuming correctly, if not, what's this wire for? Thanks in advance, Fishdady
model #j150tlcsr. I bought an older F&S for this engine to replace the blown engine that was on my Hydra-sport bass boat. Problem is no lifting ring on the engine. Googled it and found them saying to make one to use on the flywheel holes. This just doesn't sound right to me. Does anyone have a...
Helping a friend with his "new to him" boat. Straight-up, I've always been a Johnnie/rude guy, just don't hold it against me. Anyways, this Merc has Autoblend. Was wondering how reliable these are, anything I need to check (boat sat for 6 yrs). Do they have a low oil "buzzer" Guy wants to...
I have a '57 lark. problem I'm having is when the engine is running. it doesn't go completely in gear, forward or reverse. I shift it into forward, it won't go completely in gear untill I manaually push the shift arm (on the engine) forward Same thing happens when I put it in reverse. It's...
Serial # 3939199. Explanation; I have lately been buying older engines to "fix-up" I've been sticking to Johnny-Rudes because that's what I know. (I'm a novice) I did buy this Merc and I'm confused as there's a lever, right below the the front cowling, actually on the mount that says "troll". I...
I have a Johnson 140 ( mod-140tl78c ser-j4990278) I'm doing a rebuild on it, and when I tore it down, the rod part# was 312712 (should be 387831) The piston just had OMC 362969 trw 470-99 (should be 388671 std.). This is my first rebuild, so, I'm confused on these numbers. I hope this isn't...
I have a 1978 140 h.p. Johnson (mod 140tl78c ser j4990278) I had a ring break taking the piston with it on #3 cylinder. I have started to tear it down, for rebuild, and, when I pulled the intake off, found rubber wedges in reed box. In #2 cylinder, this rubber "wedge" was distorted. I have...
