[Reports he saw a video] of what looks like a 15' Mischief with an inline six-cylinder 115 running 60.2 on GPS. Looks like it is pretty stable.

If a white hull, I think that has been around for years on that site.
cbgann posted 01-29-2008 02:28 PM ET (US)
No, it is a red hull. Someone on CW was talking about rigging one with an inline 6 several years ago. Am thinking Bob K. somewhere in SW Florida.

Bob rigged his 15' Mischief with a late model Mercury 90 after playing with the idea of rigging it with an older Mercury tower. He reports his Mischief will run around 52-MPH with his current setup.
He no longer posts at this site, but you can find him on the aforementioned site quite often.

Too bad we have no URI for the video. It sounds interesting.

The 15` Whaler, 60mph video is on YouTube, but I can`t remember where I saw the link

I love the offshore video. You can hear the engine rage up when he jumps the first wave. Nice.

I wish these home videos of boats moving at high speed could get rid of the obnoxious wind blast sound.

I have no doubt that a properly rigged 15ft. Whaler can achieve 60. Back in the 80's I rigged a 15ft. center console Whaler with a 4 cyl 75hp Merc (1985) and it ran into the mid 50's. We ran a Merc high performance chopper prop, dual cable steering, and the engine was jacked up on the transom as high as possible. It was a bit of a handfull at WOT...but with a low water pickup and a jackplate I think there was more performance left. I'm sure an inline 90/115hp Merc of the same vintage would be much quicker. A jackplate that would extend the engine farther back (say 10 inches) would make the boat handle like a larger boat and enable the engine to be raised even higher....better handling and better speed due to less gearcase drag.

Hi all just wanted to update this topic of a fast mischief.
bskater24 posted 06-08-2014 11:48 PM ET (US)
That is my 1990 Mischief. I just put another motor on it last week and took it for a test blast yesterday, got 66.1mph and was surprisingly stable. I ran out of prop so am going to try a 28p Ron hill or maybe even a 30p chopper. I will post a video as soon as I can.
Anyway My gel coat is a bit faded and wasn't sure how to prepare the non-skid portions of the top deck. I saw an amazing mischief on eBay and would like to find out how make my mischief look New again. Thanks for any help, Bill

I would like to see a newer video, be sure to post the link.
Try some 3m rubbing compound or 3m Restorer wax before you go too far with the gel coat work. It may take more than one application of the Restorer.
bskater24 posted 06-10-2014 08:16 AM ET (US)
Thanks teak oil I have already tried the 3m products they didn't do the job... even tried to wet sand to 2000 grit. The red gel coat needs some help. Is it possible that Boston Whaler can help me out with such an awesome classic? What's with the red gel coat it's been in the shade and undercover in the winters for the last ten years and can't restore. I have a 1982 24 SUPERBOAT that I am putting a verado on and it polishes out like it's new. I am a little surprised about whalers durability...

bskater, my buddy Eric built the one you saw on ebay, had a fresh 115 TOP, with hull mods couldn't get it past 55, with all the tricks, it was too heavy.
Heres a link:

My 15' BLACK sport was consistently faster, and it has all the tricks to, including a keel pad and a 28" cleaver surface prop.

I think there are running videos at least on the Mischief
Jamesgt727 posted 06-17-2014 07:13 PM ET (US)
That Mischief lives in New York State on a Lake now.
Jamesgt727 posted 06-17-2014 07:15 PM ET (US)
I know this isnt the forum Jim, but I still have this if someone wants to turn a sport into a mischief

bskater, I believe you can bring back the luster and make your gelcoat look like new. The trouble with wetsanding with wet/dry paper is most folks don't start with a low enough grit to cut off the old oxydation. Also the paper whers out fast. I brought back the shine on the gelcoat on my '86 15 footer to like new usung Abralon 6" sanding disks.
http://thesandingglove.com/Abralon-Sanding-Discs.aspr
These disks were originally developed for the fine furniture buiness, have since found there way into the bowling industry, bowling pro shops use them to change the surface texture on bowling balls to match the oil conditions on the lanes. Thats how I was introduced to them. They work great on gelcoat, just start with the lowest grit(360) and work your way up through (3000). I bought a 4000 grit pad at my local bowling pro shop to go even further. Forget about that 3M restorer, and rubbing compound. When you are finished wax the surface with a good quality carnuba auto wax.
One disk of each grit is all you will need. You can do it by hand too.
