I guess now I know why you put those silly grab rails on a ski boat |

Update -
Got back home early this week just in time for yet another 60 hour week followed by a bachelor party (of sorts) this morning. However, I did get the chance to head to the lake for a few hours this afternoon to put some more hours on the engine and of course check out the tach adjustments. Tach checked out perfect so I took some mental notes on RPM vs MPH and it does indeed appear I'm right in there with the norm for what I have - 30mph was consistently reading 2850-2900 while closer to 40mph was pretty much 4000. I still think the reman prop I was given after the accident isn't quite right - seems to vibrate just a little in the upper rpm ranges. But I'm curious if I may need/ want slightly more prop anyway. As it sits she has considerably more hole shot than before the rebuild. At half throttle I'm afraid I'd dislocate some shoulders! I haven't yet tried for WOT, but the way it climbs to the upper rpm's I wouldn't be surprised if it went well into the 5000's, which I'd rather not do. |

Joe, you've been kinda quiet on updates. It's been a month.
What's happening? You're not still painting stuff are you? I found the perfect oil filter to match your paint scheme on the engine Pretty spiffy huh? |

I ran my GT-40 up to 5200 all the time.

Agreed,5200 is no problem /with a GT-40. Keeps it healthy, just limit it to less than a minute or so.

Sorry for being so quiet -- didn't realize my voice would be missed that much
Anyway, rather disappointing past 30 days or so .... at least from a lake-time standpoint. We've been absolutely swamped with work. Between heading to the Colorado project every 3 weeks or so and trying to stay on top of things on the home front we haven't had a single day to make it to the lake. Then there's all the paperwork ... which is one of a few reasons I haven't frequented the site lately either. Not really an end in near future so it's looking more and more like I'll be winterizing the ol' girl before a free day arises BTW, I like the filter - did you make that just for me?? |
