    18 foot fibreglass bow rider minimum engine size?

    Save yourself a lot of trouble for nothing but a disappointment. Forget the 65! Find yourself a 115 (prop rated) or better and get it propped right.

    Prop boat to jet boat?

    That is the synopsis of my reply, a Mercury OB commercial, in a Merc OB catalog with a 75/60 hp Jet on an aluminum boat, specially designed for the Pacific NW, on a river full of rocks.

    3 blade stainless vs four blade aluminum

    You nailed. You can bla bla all day long but the "proof is in th pudding" (how does it taste). Only way you will really know is to run it. Yes the tabs are designed to deflect water down at the transom which helps to trim the boat out and stay on plane at a lower speed with lower HP required...

    Wiring diagram for 2002 mercury 90 hp

    I agree on the sense circuitry being fed by the smaller red wire and it being high enough impedance to prevent problems. What I don't know and assume is that the regulating device is a series pass element, Silicon transistor (probably) or MOSFET and, the mechanism whereby it also shorts out...

    Prop boat to jet boat?

    Only 2 things of which I am aware: 1. Had a friend suck up his ski rope in the impeller and had a bear of a time getting it out without putting the boat back on the trailer and trying there. 2. Pumps aren't all that efficient. In outboards, the 75 hp triple 2 stroke Merc is rated at 60 hp...

    Anchor advice needed for rocky and tree bottom lake

    I used mine in lakes and had no problem with current as there wasn't any. If you maybe had chain attached and backed up hard enough.......I usually carried 100' of anchor line and never anchored in more than 25'. I think I am remembering an occasion where I couldn't get the anchor loose and...

    Wiring diagram for 2002 mercury 90 hp

    Fuse is 20 amp but not sure it would have prevented the problem. Reason being, there are 2 red wires emanating from the module with the smaller one being power"input" from the battery....aka one terminal of the starting solenoid.....(12v distribution point).... which is a low current...

    Anchor advice needed for rocky and tree bottom lake

    I used to fish places like that and I too would get the Danforth hung up. I found a Danforth that had a bent rod attachment that allowed you to drop the anchor, and then back down to set it but if hung up, you drive against the wind/current pulling the rope with you and a slip ring that was at...

    Wiring diagram for 2002 mercury 90 hp

    Geez another brain fart.....getting too frequent. With your reply, I looked at the picture again and see that the rect-regl has a hole blown in it and the wire from the starting to the solenoid is burned where adjacent to the input battery wire, but looking on towards the starter, it's...

    24' Glasply, Aluminum or Stainless.....?

    I apologize for my error prone reply. I must have had a brain fart. Getting more frequent at my age.

    rolling torque wrench

    Northern Tool, a popular industrial tool www, lists a 0-250 in-pound torque wrench for 40 bucks.....can't pull up the ad for some reason. Brand is Powerbuilt, size is ⅜ drive, Model #641432

    losing lower unit oil

    I did it once years ago. Recalling, dropped the LU and using a hook type tool, dug it out....as stated a quick fix. Sometimes drilling a hole in the metal part of a seal and using an appropriately sized sheet metal screw will give you something to grasp to remove shaft seals without having to...

    Wiring diagram for 2002 mercury 90 hp

    Geez....whadda mess!!! Looks like the solenoid pitted and welded at the pits causing the starter to remain engaged which did ok till wiring in the starter overheated, melted the insulation, shorting out internally and continuing the high current demand from the battery to continue...

    24' Glasply, Aluminum or Stainless.....?

    What are you currently running in material? Whatever it is, duplicate it with a 2" pitch reduction maintaining the diameter as close as possible to the current diameter....expect it to increase slightly as in the design of props, shallower pitch usually goes hand in hand with larger diameters...

    3 blade stainless vs four blade aluminum

    Stainless weight subject has been kicked around by big guns on here and my recollection is that it's a non issue from an engine wear and tear aspect. Yes I can see it being noisier with a sloppy fitting hub insert. The 140 I/O is no speedster in the first place. Most aluminum standard...

    losing lower unit oil

    Your tank is a fixed volume of water. Running your engine adds a varying amount of operational residue to this limited volume. Your oil is added to your fuel and fuel, an oil byproduct, are consumed and dumped into the tank along with the appropriate volume of air. All the mixture didn't get...

    Aluminum fish and ski

    Crestliner pioneered the welded hull, I think I recall reading on their www. They have an extruded tongue and groove keel (for example) where the aluminum bottom sheets tuck into the extrusion, then welded on both sides (inside and outside). I have been running welded aluminum hulls for over...

    disable auto oiler on 90hp 2000 elpto

    I agree on what you are saying here. My current Merc 115 2 stroker is a 2+2 meaning at speeds below about 2000-2500 RPMs it only runs on 2 cylinders as there isn't enough fuel to the other two to ignite into combustion necessary to consider the cylinder providing power. Once up above the kick...

    disable auto oiler on 90hp 2000 elpto

    Lubricants of today are not as they were back in the '50s and earlier, when it was the quart of 4 cycle engine oil for 24:1 vs todays 50:1. Materials are better understood for particular applications and with CDC milling machines of today, tolerances are changing from 0.001" to 0.0001" which...

    disable auto oiler on 90hp 2000 elpto

    Pennzoil super synthetic-blend TC-W3, available at wally world, is almost smokeless with 50:1 pre-mix. Only time you can detect smoke is going from idle to Firewall in the hole shot...and then it's only for the first second.....but it is 50:1, not 80:1 the ratio for those engines, per the Serv...
