    2002 Mercury 115 ELPTO 2 Stroke electrical output

    I say red because that's how the service manual addresses the different amperages of generating devices....by color.

    2002 Mercury 115 ELPTO 2 Stroke electrical output

    If the stator is red its 16 ampere rated and that is at max RPM. That is the max rating and I don't remember the output voltage when it supplies that current. Max voltage is regulated at 14.5V max under certain amperage conditions....like topping off a near fully charged battery with trickle...

    Looking for my first boat and dwelling too much on the I/O vs Outboard question...

    I fished once with a friend with a 50's era LS cabin (shell). It was a 20' with a 70 HP Merc I6 outboard, which moved it right along, just right for that boat and its use. You're getting on down the line on aluminum hulls and age. I would think that you will be inundated with leaking rivets...

    Looking for my first boat and dwelling too much on the I/O vs Outboard question...

    I've had both brands and liked both. The hulls are basically sound. Only probem is the deck (floor) and the transom wood. The Crestliner transom is highly reinforced aluminum framing, and I found that mild water absorption in the 2002 I bought was not a safety hazard. It had a soft spot near...

    Nosing down

    The Hook would be your problem. Get a "yardstick" or suitable 3' or so straight edge and get under the boat with one end of the stick at the rear edge of the transom and the other parallel to the keel pointed forward. The Hook will easily show up as a gap like in the Hook picture. If that...

    Take it back home or pay the marina for the convenience!

    How much slip does your prop have ?

    Like other props from other suppliers, like a couple of Mercury Laser (I and II) the ports are there to allow air (engine exhaust) bubbles to flow across the blades reducing the density of the medium allowing the engine to rev. faster like would happen with a shallow pitched prop. Once up and...

    How much slip does your prop have ?

    I think blade numbers and diameter would be a constant for a comparison...in short, you have a rig that has a certain engine that uses a certain range of diameters......small range and diameter change is a function of the prop design....the more "Rake" on the blades, the smaller (slightly) the...

    How much slip does your prop have ?

    I had both the Mercury 2 stroke 90 HP (I3) and 115 HP...both the I6 and the I4 versions manufactured later with loop charging. They share the same mid section and lower unit. The gear ratio on the 90 is 2.33:1 while the 115 is 2.0:1. Remembering a Merc. sales brochure back in the 1990's when...

    Mercury 75hp on aluminum 16’ Starcraft

    Charts exist showing the HP penalty as a function of altitude. 5k' is getting on up there and you may have half as much HP as you (and most of us) would have/do have at sea level. I'd say you would be looking at a significant reduction in pitch for desired performance. Prop shops will loan...

    How much slip does your prop have ?

    I use Go-Fast.com slip calculator. It has a zero slip column and then using the inputs to the chart, with your actual speed vs zero slip speed, you get your % of slip. Big heavy loads slip a lot as do cruising speeds where a lot of the boat is in the water. Easy planing boats with the right...

    1986 2 stroke 3 cyl major issue

    I used to run my tower of power high in the water with the prop partially out of the water as I could hear the blades beating the water making a humming noise.....as you mentioned I too developed a leak in the water jacket cover and never thought about it was due to running like I was. Live and...

    Mercury 75hp on aluminum 16’ Starcraft

    Nobody (as I could tell) mentioned trim tabs. Your comment about people sitting in stern seats....aka adjacent to the engine just magnifies your stern heavy condition. Next the load you are wanting to carry in that boat is a lot......a lot more than I would expect to have in that boat. Next...

    Birds in the boat . . .

    Looks like a Wren. I had one (apparently) that decided to make a seasonal home in my shop. Been about 5 years now. A very busy bird when she has babies in the nest. She has a beautiful voice. This years 3 hatchlings have just left the area on their own. Spiders have all but...

    Mercury 2.5HP Outboard Not Moving Boat?

    Is water moving out from behind the engine when you apply throttle? No, then prop isn't being driven as suggested above or engine isn't shifting into F gear like you are telling it. Yes, 15" lower unit on a 20" transom would be a problem. Need new water in front of the prop to get propulsion...

    Back for More! Looking into a bigger boat for big water - Deck or other

    My family grew up with larger boats too. Got to the point where it was too large on land and too small on the water. Finally quit searching for the ultimate solution to both conditions.

    Engine height

    Well sir, that depends on the boat and what's in it. I had an 18' alum. bass boat with a 90 Merc. and SS Ballistic 24P prop., 1 hole up off the transom. The picture in my Avatar is that boat kissing 50 with just me. My fastest hole shot was with the engine at 90* to the hull. Hole shot was...

    More Speed - for fun.

    With all that said, correct trim position IS definitely a BIG part of how a prop (any prop) performs on your boat!!!!! There is a correct position for your hole shot with your water toys, and a totally different position for you wanting to get max speed out of your rig......regardless of the...
