    Pulling Tool Experts.-

    Need to remove a thrust washer stuck on prop shaft, have tried almost anything but won't budge or loosen a bit. My fingers won't go inside prop's round housing to grab and pull washer out. Can someone recommend a nice puller that will fit inside housing. Will I need a 2-3 claw puller. Thanks id...

    dory 11ft and yamaha 9.9hp

    Why did you shimmed transom up in the first place ? it's a L shaft OB for a S transom height ? Forget all about AV plate talk, word of mouth that has to be even with lower keel/hull, says nothing as won't know at which lower leg height water flow at speed passes by when hull rises out of the...

    Silvertip, +2 on your tech appreciation, With driver weight distributed max forward sitting in middle deck and throttling with finger nails at 4700 wot rpm the boat did nothing, simply stayed there at slow displacement speed at just 10 Km/ with slight bow up. With 4700 wot revs and a...

    Prop Maximization.-

    Nope, the post is not a trick, the pic is a real boating example. It's an essay that will show the difference between prop theory and water practice. Think less, have swapped an 8 prop for a 7 one, both alum 3 blade OEM props.. Shoot your best answer on how much wot rpm OB has gained and if...

    Bow lifitng way too high on 13ft SmokerCraft

    Is OB tiller driven, or has a center console ? That combo has too many issues : -OB seems is a XL shaft, middle body is way long ? -Being long, lower leg is producing extra water drag in terms of rear transom water splashes which slows combo down. -Definitely needs a transom mount to raise OB...

    Portable inflatable boat

    There you have it, was a 375 not a 365, so it's a 3.75 Mtr light Rib. Tubes are low-rim ones. Folds in 3 pieces, just unpack, unfold, bolt internal deck hinges, inflate all tubes, install OB and out you go. Reverse procedure when back. Excellent alternative, will outrun any other alum...

    Ventilation on corners 40 HP evinrude on 16 FT Aluminum runabout

    Rob, As won't know which is the ideal OB/transom height for that old OB, check modified pic to illustrate better. If with prop aeration at close turns and on choppy waters, water flow at speed is passing right over AV plate (red line) if you remove alum block to lower OB downward and...

    Correct prop size on new boat

    Hard to tell, seems hub is already shot....a hub slip test is required to determine so... Remove prop, mark a straight line or 2 dots as in pic, go for a short wot spin as loaded, remove prop and check if marks have moved away from each other, if so, hub is kaputt!! Need a new prop. Happy...

    Honda BF 2.3 outboard motor compatibility with a Walker Bay 8'4" plastic dingy .

    Darren, what a bummer having split shaft recommendations. With either a S or L shaft OB boat will have propulsion, "will it be top one" ? Will depend entirely on water bed height lower tail deeps in to achieve best prop thrust while OB sits on transom, as this is a very under powered OB powering...

    Seamax Return.-

    I'm beginning to think that combo is somewhat cursed, first was the SiB with full tech flaws, now the tach & OB. To make the long story short. Owner swapped factory delivered OEM 13 pitch prop for same OEM 11 pitch prop. Installed new prop, went to test it. The difference found is quite...

    Lack of Information.-

    Owner swapped a OEM 13 pitch prop for same OEM 11 pitch one. As usual removed old prop, greased well shaft splines and inserted new prop. With nut adjusted tight, prop had a 0.5 mm lateral play. Went for a test at speed, not wot though, sea cond was wavy, windy. Some time after there was a...

    Pontoon Mercruiser 140 Prop

    Your friend fixed the prop problem installing a new one due to being kaputt the previous one, that's for sure. Make a prop slip test on yours. Remove prop, turn it upside down, mark a straight line or 2 dots facing each other with a white marker, Install back on OB, go for a wot spin as if...

    I swear...

    Bingo, With OB sitting at the sweet lower leg/transom height the only issue left for a correct transom optimization/prop maximization was finding a 8.5 pitch prop to lessen a bit my OB slight over revving with 2 up and bit worse solo boating, that's at full grip running a 8 pitch prop. A...

    Pontoon motor height question

    What have found selling boats, engines, rigging combos, optimizing OB heights and being a boater myself is : Not all hulls floats same when on plane, some deeper, some higher, depends on hull shape, weight. Not all boats have same transom height, doesn't matter if being short or long, have...

    To decarbon or not to decarbon ?

    Roberthill, Thanks for your kind words, much appreciated, wanted to thank you too for testing CRC Engine Tune Up. Find that too many boaters on this forum likes going per assuming things, word of mouth or plain theory in many boating topics, instead than testing practice results which is the...

    Propellor? or engine set up issue?

    That prop is SHOT/KAPUTT go for a new one, clean prop shaft and grease it well with marine grease prior installing a new prop. As you haven't tached current prop when new as usually loaded won't know if it's OB runs at mim-max wot rpm range factory stated. So the dilemma is : buy same one or...

    Honda 130 not peeing

    Plainly understand that's impossible to flush OB's with fresh water after use. The issue is that moored OB's on salt water use will collect thin salt layers one on top of the other due to hundreds of hot/cold cycles when in use. Remove boat from water and flush each OB with Salt Away Product...
