    Ok you old salts...Merc question

    Was surfing old Merc sites. Question came to mind. Back when the first tower came into being it was a 60 hp and 99.4 cu in (as I recall). That was '57 or somewhere around there. 25 years later the same powerhead is putting out 150 hp with the blue band, with the old hp ratings (brake hp just...

    Couldn't believe my eyes.

    Was leaving the lake yesterday and this toon was launched by 2 middle aged ladies and a gent. Know not who owns the boat.......I think one of the ladies (and her husband owned it) and her husband usually does the driving but apparently wasn't aboard. They got it launched and beached. All...

    Posted Octane Numbers

    Just got back from a trip thru New Mexico and Arizona. On the northern leg of the trip I noticed the gas pumps dispensed 86 and 88 octane fuel whereas I am used to 87 and 89 in Texas, which is also what they dispensed in the lower parts of the two states. Since my outboard and truck run on...

    Trivia. George C. Scotts Boat MOJO Accident

    Some time ago someone showed us a pic of what was said to be George and wife exiting the Columbia river in NW USA into the Pacific in the MV MOJO. This huge (normal for that area with what I hear) wave smacked them and pitched the bow up at about a 45 degree angle......this is a 65 ft boat...

    Hey Kenny

    Help me on this ole buddy. Was playing some more over at the Merc Prop site and gave them a set of parameters. They came back with a High 5 at 12 3/4 x 24P or a Trophy + 13 3/4 x 24P (4 blade). Confused as to why the inch drop in diameter when upping the blade count for the same set of...

    Boy I'm really confused now

    It's raining outside 8) 8) 8) 8) (drought is busted!!!) and have nothing to do so I'm surfing. Over at the Merc prop selector site and put in all my data. Currently running a 24P at 5600 rpm's. WOT upper limit for engine is 5500 (big deal). So Merc comes back with a 4 blade Trophy + at...

    Iboats props going fast

    When they say limited time offers they mean it. I bought my last 2 props off here at a great savings and they said limited time offers. Today I looked again (really looking for one of Kenny's new props.....Enertia I think they call it) and the top two props for my engine 23 and 24P are no...

    Moderator Intervention time......PWC conversations belong on PWC page, not boats

    Like I said, things were quiet and pieceful here till a puke came over here looking for sympathy because he pulled one of the PWC stunts and turned in front of a boat. Well he didn't get it and the place has been an uproar. Time for some serious supervision to takeover!!!!! Mark

    Hey Kenny, More Trivia

    I was just reading one of your replies and got to stareing at your propeller. At first glance it was turning cw. But after staring at if for a few seconds, I could look on the right side and it was still turning cw. Moving my eyes to the left side I could make it go ccw or cw. d:) No I...

    For Those Wanting to Get Technical

    Was over at www.mercurymarine.com awhile ago brousing through Chapter 4, Propeller technology. If you haven't been there and want to know all the why's and wherefor's in designing propellers this must be the place. Very comprehesive d:) Gotta laugh here. In their dissertation, they mention...

    Antiventilation/anticavitation Plate Rhetoric (Trivia)

    I was raised to call the plate on top of the prop an anticavitation plate. Some time ago, on here, I was corrected and told that it was an antiventilation plate. Did some checking on the definition of the two and agreed with my mentor that I should be referring to it as antiventilation. So...

    Kenny.....Emertia question.

    Did a www on Mercury Enertia Propeller. Came up with a thread from Yachting Mag (as I recall) that said something about X7 metal that no one else had for this prop which is the reason why it's so special. They also mentioned aluminum. Is the Enertia an aluminum prop? Thanks, Mark

    Rollers saved the day

    Bought a used boat. Had 2 bunks; no keel rollers. Decided to add keel rollers to aid in "driving on". Glad I did as the last time I was out when I went to retrieve the truck/trailer, I noticed the rear of one bunk had broken loose from the trailer. I tried to tie it in place to reload the...

    Gotta put this here in props.

    I know that I have been involved in a lot of yakin lately about my setup, and it's (deliberately) a little Mickey Mouse setup. I also know that there are about 80,000 members of iboats. I know that some are yakers (like me) and some just surf; some are regular attenders, and some just jump in...

    strange prop blow out.

    I have experienced similar things when hole shooting with the engine trimmed out; generally speaking. Trimming in cured it. I do know that the Hustler has a very good cup and also has (mine does) vent holes. I know that if I am trimmed in tight the vent holes do nothing. I have to trim out...

    1996 Merc 90 hp, low power and only 4000 RPM

    Very possibly there were some finer black particles that made their way to your carbs and are clogging up your venturi jets. Dropping the bowl on one should answer your question. If you see anything in the bowl you can figure the carbs are clogged. Also, be sure to put something under the...

    79 Evinrude 70

    With the info you have supplied this is just a guess. Just because you pumped the bulb doesn't mean the fuel got to the combustion chamber. Could be a clogged fuel filter (if you have one) or clogged carb. What it does say is that you are suffering from fuel starvation. I'd chase gas before...

    73-74 merc 1150... 115 hp

    Not a lot of info provided to think on, but I have had a woodruff key in the flywheel-crankshaft interface shear on such a thing as a backfire and die, or hitting a submerged obstacle. That will affect your timing and definitely affect your ability to start the engine. BTDT Now if you are...

    Pusher vs performance prop comparison

    Well, the adm guys got my login straightened out after the transition and now I'm back in and rearing to go. This is long, but I think educational for a lot of folks; otherwise I wouldn't be "wasting my time". For those who haven't heard of/followed my prop caper, I decided to buy yet another...
