We have a 1999 FourWinns 190 Horizon, 4.3GL PWTR VP engine. We had several repairs done to the engine in the past two years. The most extensive repair was when the engine was removed, rebuilt, and re-installed due to a head gasket failure two seasons ago. The engine performed ok for a few months after the repair, but then started having problems starting. Overall it seems like the starter is encountering some resistance when it engages. It will just barley start after a few attempts. Once it starts it runs just fine. The mechanic that performed the engine overhaul has since also performed the following additional repairs, but the problem continues: 1 – Replaced both manifolds and risers 2 – Replaced the starter twice 3 – Replaced the flywheel We performed a diagnostic on the electrical system and ruled out any electrical system issues. Last fall we were able to get it started after a few attempts in order to winterize. We will be getting it ready for the 2017 season in a few months. Any ideas on what we should look at next? Would an engine compression test be worthwhile? |

Without a doubt it would be a good idea. Are you getting any water in the cyls? Check by disabling the ignition, remove all the plugs and crank the engine over. See if water comes out of any of the cyls. Also check the plugs for rust on the electrodes. That would bring you back to the head gasket job. However, there are many other causes of hard starting. Check ignition first and then fuel system. But for sure make sure the engine is not sucking in water. |
