checked the spark plug wire with a tester,there is no spark.the boat lost power and when I got it home it wouldn't start anymore.It had a very strong smell of fuel when I was out on the water.could a coil do this? |

Yes, but there could be other things as well: points or electronic ignition damage, rotor, cap, loose wire between the ignition key and the coil, broken timing belt (on 4 cyl OHC engines) are a few of them. |

Thank you for a quick response. I have power to the coil,and the wires are new as are the cap and rotor.Which belt is visible at the front of the motor? I am going to try the coil and then go with what you suggested,points and electronic ignition. |

I am a firm believer in using the P of E.... process of elimination.... one item, and one item at a time ONLY, until you isolate the problem.
However, in your case, ignition components are confined to a small area, the cost will not break the bank, and it is never a bad idea to replace ALL.
With the cap removed, and a plug wire installed directly into the ignition coil, and with a spark plug connected and carefully placed where it is grounded to the engine block......., you can simulate your ignition spark by manually operating your contact points with a "non-conductive" instrument. (ignition switch must be ON)
Watch for spark at the spark plug!
The spark that you want to see will be white or whitish-blue only. No yellow.
(If electronic ignition, it is a little more technical, but can also be done.)

Thank you very much for the info. Maybe I didn't gap the points correctly. I will go and try your test,do I use a tool to open and close the contacts? |

Thanks again Ricardo,it appears as though my engine has jumped timing.How does that happen? could it have been the results of me starting the boat over and over before I replaced the starter.Is this a simple fix or does it need to be done by a dealer? All of the tests were done with the help of a friend of mine who is a mechanic,the good news is the compression was perfect. |

Paul, I don't see any mention of which engine this is!
If OHC 4 cylinder engine......, then yes..... the belt can jump on these, and particularly if the engine were to back-fire and/or kick over a little bit in rev direction.
Just yesterday I repaired one that had jumped a cog on the counter shaft driven pully.
The owner opted to have me re-index the distributor (appose to a more timely tear-down to access the entire belt system!)
I'll be making a note for his maintenance log to this effect.
The belt is relatively new, so it will be a while before a replacement is needed.
Mean time, I'd want to make sure that there's a note to this effect for the next guy.
There is no harm/no foul to run one this way....., other than;
a) the counter-shaft indexing marks no longer align.
b) it will require that the next mechanic doing a new belt figure out that the distributor indexing must be put back to original.
(Camshaft cog would be a different story)

AQ 131a the belt looks new.Thanks again for the quick response.
All of this started to happen right after I put the new starter in.I was on the water and I noticed it was hard to start and then I lost power but was able to make it back to land,the next day there was nothing.I got frustrated when the old starter was going bad so I was popping the ignition when the starter wouldn't turn long enough not letting the motor stop before I tried to turn it over again. |

The timing had jumped,I was told the belt was too sloppy. Boat runs great now! I recommend that everybody use the information they get from this forum,it helped fix my boat. |
