    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...

    oil oil oil

    Here we go again. What occupies more shelf space at the retailer than oil....bread? beer?<br /><br />I'm not a purist. I have a dozen types on my shelf and can never decide just which one I will use where and when; nor can I decide where to put my hand when I am in the store (usually WW as...

    Promised I wouldn't but I lied

    So today I'm trying to figure out how to calculate prop pitch, from a layman's standpoint. Thought I knew how to do it......yeah right! Had a guy who wanted to know and thought I was just thing to help him out.<br /><br />Fiddled with props (and other things...calculators, rulers, compasses...

    Okaye; a new twist to an old topic

    I know that you're bored to death with the Ballistic senario. So here's a new twist.<br /><br />I didn't like the clutch racket (banging and clanging at idle in gear) on the high pitch SS props that I have discussed several times.<br /><br />In talking with the local Merc Tech, he said that the...

    Well I just looked at the comple lineup.

    I know you guys are trying to help me get out of this Ballistic rut that I'm in (or am I), but I have a problem. I have a light fast boat and it is Merc driven and only 90 hp.<br /><br />This disqualifies me from purchasing some of the more popular names you guys mention. They're made for...

    Confusing data....Kennnnnnnnnnnny

    So Friday I'm out in my boat and run her up. Water temp is now 80 degrees. Instead of the 52 I got in January, I'm getting 50. <br /><br />I understand the why on that, but what I don't understand is that the rpm's are the same at 5600. If hotter ambient temp reduced engine performance, why...

    Last Time and I'll Shut Up

    Came on here in Dec and you guys were talking about Sea Foam and decarb. Blew you off.....but kept seeing yakin about it. My recently acquired used outboard was in need of a shot of something.<br /><br />Finally gave in and bought some. Put it in the OB and walla. Convinced it's good. <br...

    I keep harping on this butttttttt

    You guys taught me about Sea Foam. Can't believe I spent my whole life associated with mechanics and things of the sort; am a lube nut, and never heard of the stuff before you guys talked me into using it.<br /><br />So yesterday I'm running the 2 stroke weed whacker. Kinda hard to start and...

    Absolute Max RPM's on 2 stroke

    Been a lot of yakin about WOT max rpm's and I have been surely involved as I bought this boat in December, '05 and it had a 17" pitch prop.<br /><br />The engine is rated for 5500 WOT upper end. I had to go to a 24" pitch to get the rpm's down to 5600 and this is an '02 engine (stock 90 hp 3...

    I know I'm hard headed, but I just don't understand.

    Was reading the 175 entry Ron G tune up report just now on this forum and noticed the Ballistic bashing.<br /><br />Well you guys know as you were there and I wasn't. You were running the rigs and I was out of it for the last 10 years.<br /><br />So I buy this 17' 3 step, padded, tin BB (boat...

    Yielding to the Power

    Ok you guys. <br /><br />Back when I joined this forum, after just buying this used boat, you told me to keep my stat (which I had removed because the old one stuck closed) and decarb (de what? had never heard of it). Well I resisted and finally, after a couple of months of membership I...
