Post subject: | 2001 Horizon 200 engine removal and coupler replacement |
Hi everyone! I'm new to this forum and would like to share my experience removing the engine and replacing the coupler in our 2001 Horizon 200. The job would not have gotten done without knowledge obtained from this forum and thought I'd share details learned along the way. Backstory We bought the boat just a few months prior to the coupler failing. Long story short: CHECK YOUR GIMBAL ALIGNMENT!!! I am 100% sure the coupler would not have blown had I checked the alignment. Root Cause of Coupler Failure After putting the engine back in we found it out of alignment by about 1/4"! This distance is more than you could ever adjust out. After scratching our heads for half a day, we pulled the engine (for the 2nd time) and found a 2nd set of washers on the transom shield underneath the motor flange. The washers that were originally found in the right place (above the motor flange) were not the correct spec (too thin) so it is highly likely the person who last pulled the motor placed the washers on the transom after pulling, put the engine back in and couldn't find them so they replaced them with another set.

This is why, I have said for a long time you really should be pulling the drive and checking alignment. In this case you would have not been able to avoid the repair because the when the engine was replaced the wrong washers were used, but in most cases if you are pulling the drive once a year or at least every other year you will know it when its off, and can investigate why. If you buy a new boat it should be done while under warrantee and a new to you boat should be done as well before you start using it. If you do this regular maintenance the gimble bearing, u joints, the drive itself will all last much longer. Leave it on and never check will result in a big enough bill to make some just sell it. |

Totally agree! Once you get over the initial hump of building or buying an outdrive cart and alignment tools, it really isn't that bad of a job. Also, given the pressures involved on the spline, a grease high in molybdenum disulfide (e.g. Loctite 51048 Moly Paste Anti-Seize Compound) should be used on the spline instead of regular grease. |

thanks for taking the time to write that up! Don't think its something I would tackle but its folks like you that share the information that might make it possible. |

I hope this post encourages people to start doing their own drive service once a season since it is not really hard or technical and can help you avoid expensive problems. In 18 years of ownership I’ve replaced the gimble bearing once (leaky bellows) replaced the bellows 2x (2005 & 2016) and the drive still has the original u joints. And I have not had to change the alignment in all this time. You just need normal hand tools, an alignment tool and an outdrive cart. |
