Sort the comments below by OLDEST to see a chronological timeline of the work we have completed so far.
A client from Pennsylvania brought this vessel to us in hopes that we could figure out a miss that was occurring in his engine. Another shop had done extensive work on the engine after an unfortunate electrical issue, but the engine still isn't running quite right. We'll do our best to track down the issue, and fix a few other little things along the way.


We completed the water test today, and it seems to be running well!
This boat's engine miss is about to drive us crazy! It has severely shocked our lead mechanic right through his timing light, and we've been working directly with PCM to diagnose and fix the issue, and we're still fighting it! Normally we knock out engine issues on these boats very quickly, but this one is tough. We believe we have tracked down the cause, finally. We'll be water testing again on Wednesday. it seems to be running much more smoothly now on the hose.
The new fender is on, and the side steps of the trailer have been securely welded into place properly. A crack in the trailer frame was also found and welded. Glad that was noticed!
New harmonic balancer is on. No pictures (I forgot to get them before the installation), but it is ready for a water test and timing adjustment now, finally.
This boat's trailer was missing a fender when it arrived, and the owner asked us to replace it. We ordered the replacement from Boatmate, but unfortunately the whole side step area needs to be rewelded before we can mount the new fender. We'll have that done and then get this installed.
