| Post subject: | So I hit a rock |
I took the boat out this weekend. Noticed a slight vibration (could be a low rpm miss). But the I hit a rock took a small chunk out of the prop and the vibration got worse especially when turning left. I pulled the drive today and the gimble bearing seems smooth and the ujoints feel good. I think I need a prop. It is a 1989 h200 with the 5.8l stock is a 19 pitch 14.75 I think. There are lots of aftermarket on craigs but not the same what does what? and has anyone else had luck on this boat with a certain size and pitch? |

Was the performance of your existing prop what u wanted prior to turning it into a plow, which happens to us all sooner or later. If so get it repaired and buy an aluminium prop for spare. |

You definately need a prop, whether it's your old one repaired, or preferably a new one, you are still better off with the non optimal pitched prop than one that causes a vibration. Lets consider what a vibration is in relation to drive components, it is essentially an unbalance that causes undue wear and tear on moving components. In the short term there are safety measures in check, which will protect the vital components, however although these are life extending components (bushings etc.) when these components are faced with an out of balance condition they wear quickly (similar to an annodes functionality)leaving the major components of the drive unprotected, and through continued exposure, extreme wear and fatigue will ultimately cause the major components to FAIL. This will result in many more of your hard earned dollars to be spent to rectify the problem. As for your prop choice if you are unsure how it should or will perform stick to the more forgiving, and cheaper aluminum prop which is close to, or the same as the one you have incidently damaged.

I have a similar boat but with the 4.3 V-6, they came with a 15" x 17 pitch prop, the V-8 models came with a 14.5" x 19 pitch. |
