    Might have it figured out.....again. Resistor wire.

    Well as you guys may know I have been having some problems with my new engine. At first I was just having a problem with bogging at over 4K RPM. Then I was having a problem where only sometimes it would bogg at 3K RPM and not want to go over 3K RPM and it would backfire. These problems were...

    carb condensates really bad

    Didn't want to steal FillupD's thread about his air cleaner condensation but I have been wondering about the same thing but on my carb which is an Edelbrock 1409. It always condensates really bad on the outside of the carb. But I noticed when I was looking down the throat of the carb while...

    6 hours on brand new prop and spun hub/white haze?

    I got a brand new SS prop last week. When I went to put it on it wouldnt fit and when I brought it back to the prop place they looked at it and said the hub was not in all the way. They put a new hub in it for me. There was a sticker on the prop when I picked it up that said to let it sit for...

    Quick question. Can I mount electric fuel pump before fuel/water sep filter?

    Think I might be having a fuel pump issue. See http://forums.iboats.com/showthread.php?t=432099 I am only getting 3.5 PSI at idle through WOT. I have been reading that electric fuel pumps are not good at pulling fuel. They are good at pushing fuel. Can I mount my electric fuel pump before...

    Engine acting up again today. Thought I had it figured out,My fuel pump test VIDEO

    I thought I had all this figured out. I was having problems with the engine bogging bad in the last 1/3 of the throttle. Then sometimes it would start backfiring at over 2500 RPMs and not want to go over 3K RPM. I did a tune up on the dist, replaced the IGN coil, took the air horn off the...

    Can you tell a marine cabr from an auto one by looking at it?

    I got the carb off of my old engine and I found out that its a Weber but googleing the numbers on it doesnt turn up anything. I have an Edelbrock 1409 on my new engine and this carb looks pretty close to it. Question is the vent tubes that everyone talks about that on an auto carb vent excess...

    Anyway to run compression on engine without starter etc?

    I am going to be bringing my old engine back to my house sometime soon. I should have run compression on it before I took it out. I knew it was something major and long story short I decided to spend a little extra money and get a new engine so I knew what I had. Right now the engine is...

    Setting carb idle mixture screws with a vacuum gauge?

    I read you can use a vacuum port on an auto carb to set the idle mixture screws. I obviously dont have a vacuum port on my marine Edelbrock but is the port on the intake manifold a vacuum location I could use? Im talking about the one that has a hose going to it from the starboard side valve...

    Dwell keeps changing which makes timing off?

    With the help of this forum I tuned up my dist (thanks Lou) installed a new coil and checked the carb over. The manual says dwell should be between 27-31. So I had it at exactly 29. I then set the timing to 8 BTDC. Took the boat out and it has ran great. Put another 20 hours or so on it...

    This means clogged fuel tank vent?

    I was putting gas in the boat today. It was at little less than 1/4 tank. When I started pumping the gas started coming back out of the fill hole. Even if I tried to go slow it would start coming back out of the fill hole and the hose. I had checked the fuel tank vent before by blowing in...

    I have read every word on the Cobra on the Hastings site. I have followed his procedures for checking everything out and I still cant seem to get this thing right. The shift cable was replaced in march. I disconnected it at the engine and it does move freely and like a new cable should. I...

    Electrolisys on old prop?

    I picked up my new as prop and my old alum prop today from a local prop shop. They remanned the old alum one so now it's a very nice spare. But they also said that there was some signs of electrolysis on the old prop. I do not have a zinc washer on where the prop shaft is? Do I need one?

    Does this sound right about a coil and resistance?

    Ok so I saw a few of us here are having some of the same problems and putting a new coil in has seemed to solve it for a little while, until it goes bad again. I replaced my coil and now the engine runs great. But I can still feel that the coil is getting hot. Not as hot as the last one but...

    New prop doesnt fit. Store I bought it from seems giving shady advice.

    Well, per my earlier thread about my prop slipping I went out today and bought a new prop. I bought it from Marine Surplus. They are a store that is exactly what theyre name says. They stock a BUNCH of surplus marine parts they get from wherever. They have TONS of props, and they told me I...

    How to adjust omc shift assist?

    I have been looking through the manual (Seloc crap, looking for oem one) and it tells you how to test the ESA module to see if it's bad but it doesn't tell you how to adjust the little rocker arms that engage the shift assist. I have been having a problem where sometimes it will shift fine then...
