I own and operate a fab shop in north central MN. We work on almost all brands of wheel houses. The problem is not so much of what kind of grease but rather the fact that the pivots have grease fittings in one place around the radius od the pivot. This would work great if the pivot moved all the way around 360 degrees. However it only move about 90 degrees thus it doesn’t get grease all the way around the pivot. half of it is dry and rusts causing the pivot to freeze up. I would suggest adding a fitting 180 degrees around the pipe from the factory one or remove the pivot yearly and apply grease to the entire pivot 360 degrees.

The lakes I am looking at fishing have a tremendous mayfly hatch generally in early june each year. I believe they are there however the one lake in particular is a very sandy lake, however with a camera I have determined that down at about 30 feet the bottom content doesn’t seem muddy rather a much more of a silty sand. I think its possible I may be on the right track. Thanks much for the insight.
