High RPM's..low speed???


HutchBucks

Question

Took daughter out tubing on Monday...after we were done thought I'd open it up across the lake. Ran very high rpm's(up to 7 grand,usually warning beeper goes off at about 6200-6300,never went off) and couldn't seem to get much for speed(only 25-30mph, usually can get 40-45mph).

This is on a 2005 115 Merc OptiMax...What could cause this to happen? Spun hub in prop? Maybe something else? Also, how do you check to see if prop is spun? confused.gif

sounds like a spun hub...

If you have a spare prop, put it on and see if it happens as well. If it does, it's not a prop issue. If it does not, I think your problem will be found.

Your motor should have the new plastic hub system so I doubt that it is the hub. If it is an older rubber hub prop, maybe. Maybe weeds or something else wrapped up on the prop?

I believe theres you have a choice of a solid hub or the conventional pressed rubber.

If your sure the outboard wasn't trimmed to high, or had weeds or grass on the prop of around the cavitation plate, then take the prop off and have it looked at.

      Very low, probably 2 feet lower than last year at ice out.

      I might have missed a guess, but here are the ones that I noted:   JerkinLips – March 27th, then April 7th Brianf. – March 28th Bobberwatcher – April…. MikeG3Boat – April 10th SkunkedAgain – early April, then April 21st   Definitely a tough year for guesses, as it seemed to be a no-brainer early ice out. Then it got cold and snowed again.

      On the south end...   Lots of ice on the main basin, but it is definitely deteriorating.  Some anglers have been fishing the open water at the mouth of the Rainy River in front of the Lighthouse Gap.  The rest of the basin is still iced over. Pike enthusiasts caught some big pike earlier last week tip up fishing in pre-spawn areas adjacent to traditional spawning areas.  8 - 14' of water using tip ups with live suckers or dead bait such as smelt and herring has been the ticket.  Ice fishing for all practical purposes is done for the year. The focus for the basin moving forward will be pike transitioning into back bays to spawn,  This is open water fishing and an opportunity available as the pike season is open year round on Lake of the Woods. The limit is 3 pike per day with one being able to be more than 40 inches. All fish 30 - 40 inches must be released. With both the ice fishing and spring fishing on the Rainy River being so good, many are looking forward to the MN Fishing Opener on Saturday, May 11th.  It should be epic. On the Rainy River...  An absolutely incredible week of walleye and sturgeon fishing on the Rain Rainy River.     Walleye anglers, as a rule, caught good numbers of fish and lots of big fish.  This spring was one for the books.   To follow that up, the sturgeon season is currently underway and although every day can be different, many boats have caught 30 - 40 sturgeon in a day!  We have heard of fish measuring into the low 70 inch range.  Lots in the 60 - 70 inch range as well.   The sturgeon season continues through May 15th and resumes again July 1st.   Oct 1 - April 23, Catch and Release April 24 - May 7, Harvest Season May 8 - May 15, Catch and Release May 16 - June 30, Sturgeon Fishing Closed July 1 - Sep 30, Harvest Season If you fish during the sturgeon harvest season and you want to keep a sturgeon, you must purchase a sturgeon tag for $5 prior to fishing.    One sturgeon per calendar year (45 - 50" inclusive, or over 75"). Most sturgeon anglers are either a glob of crawlers or a combo of crawlers and frozen emerald shiners on a sturgeon rig, which is an 18" leader with a 4/0 circle hook combined with a no roll sinker.  Local bait shops have all of the gear and bait. Up at the NW Angle...  Open water is continuing to expand in areas with current.  The sight of open water simply is wetting the pallet of those eager for the MN Fishing Opener on May 11th.   A few locals were on the ice this week, targeting pike.  Some big slimers were iced along with some muskies as well.  If you like fishing for predators, LOW is healthy!

      Early bird gets the worm some say...   I have it on good authority that this very special angler caught no walleyes or muskies and that any panfish caught were released unharmed.
