    Hydroplane fin

    I ran an 8' wooden hydro...stepped hull with a 10 HP Scott Atwater, all stock including 2 blade alum. prop, without a fin and never felt that I needed one when I was a kid...my first boat. Maybe the step made a difference, I don't know. Only fins I have seen were mono-hull, semiVs and it was...

    15a fuse blows immediately on mercury 60

    Other than mentioned above, follow the lead leaving the fuse and find connections attached to that point. Remove all but one and start with that connection. If the fuse holds, start adding wires one at a time and testing. Your problem circuit will raise its head. Then we will help you...

    15a fuse blows immediately on mercury 60

    Good point here. A corroded fuse to connection interface becomes a resistive element. Pushing current through a resistance generates heat and heat from over current conditions is what blows fuses. If the heat is coming from the fuse to terminal connection it has no way of knowing what is...

    NGK BUZHW-2 replacement

    I had the last year of the 115 "tower" manufacturing. Folks on here said that was 1988 but my engine's title said 1989. Regardless, I bought the rig new in 1989 and kept it 7 years. Did nothing to that engine but add gas and oil. It loved 6k RPM on my Ranger. At WOT, on the pad, I could...

    Too much motor on 11ft aluminum boat ???

    " My only worry is overpowering the boat. Definitely don’t want to loose the motor or flip the boat somehow." If you did that....something stupid.....I sincerely doubt that the 2 HP difference would be the deciding factor!

    1997 Landau 1650 need more speed

    I had a 16' 11" Ranger 680C Ranger Fisherman with the high deadrise, standard Ranger 6" setback transom (from the end of the pad), and pad like their bass boat series, just a higher deadrise at the transom and narrower width. Ran a 1988 tower of power 115 with an original 24P Laser. On my...

    Too much motor on 11ft aluminum boat ???

    I had a 10-11' Alumacraft semi v rounded chines and ran a 5 1/2 Johnson on it......slow and sluggish. I sold it and later bought another boat. It was a 10' "Lake John" built by a popular aluminum boat mfgr......just remembered and edited: Lowe brand. I ran a Merc 7 1/2 on it and it was a...

    1997 Landau 1650 need more speed

    Not necessarily. I had an all stock rig: 17 1/2 Fishmaster Travis Edition Bass Boat With a 2002 2 stroke 90 Merc running a Ballistic 13+x24P at 56-5700 RPMs kissing 50 GPS. Avatar is a picture of the wake.

    Quicksilver prop query

    I have an early model Laser II with the square ports, 13+x20. The hub is pressed in and ran on my 2002 115 on a Crestliner 1750 with the same size gearbox as your 75, just used a 2.0 gear ratio. If your boat isn't loaded down with a lot of coolers and lunch. and the engine is putting out the...

    15' pathfinder tunnel hull issue getting on plain!

    Does this picture tell you anything, i.e. 60 ponies, not 40, 4 blade prop for better grip and usually the blade shape is designed for stern lift, not bow lift like most 3 blade SS props......with the HP to twist it.....your comments about RPMs in the hole shot is typical of 2 strokers when...

    Low RPM's and looking for higher top speed

    Carl Kiekhaefer originally used 2 blade props on his engines as the fewer the blades the higher the prop efficiency due to turbulence disturbances in the blade area caused by multiple blades as I read in historical records. So, theoretically, one should expect a drop in RPMs with the extra...

    Low RPM's and looking for higher top speed

    Ok bro. What's the difference in the HP of the two boats and transom area weights? Your wakes tell me that the 2 stroker had a lot more ponies and yes that did result in a super fast hole shot and 50+ MPH chine spray "fog" or faster. No doubt the 2 storker was fast, give you that.

    16ft Glasspar w/65hp 2 stroke

    Prop shops can and will loan you a prop for testing with the requirements that you return it, if not the right answer, with it in the same condition in which it left their shop.....so they can sell it as new to another customer. If you want to start with the prop listed in the tests you...

    Low RPM's and looking for higher top speed

    Sloppy hole shot???? I don't think so. Looks pretty fast to me and MPH are right up there looking at your chine spray pattern and the distance of the transom convergence behind the boat. Looks like setup as in your picture, you have the best of both worlds.

    Low RPM's and looking for higher top speed

    Agreeing with Scott. You can't have your cake and eat it. Both conditions you want to achieve are opposite polarities.....i e, you have to sacrifice one to get the other. I'd say getting the RPMs up should be your goal and suffer a few MPH less than you are currently getting....unless you put...

    Change prop or leave as is

    Don't fix it if it ain't broke! Doesn't sound like it to me!

    V-Hull Vs Flat bottom Speed

    I had a friend with the 3 HP (tank on top of the engine) with the lower unit that was essentially weedless. We went to some fine weedy. Lilly Pad infested backwaters with that engine and caught some trophy bass......but as said, it took a long time to get there.

    Best way to waterproof plywood transom

    If you are lile me, you will die before you have to replace the treated wood....or be in a different boat.

    V-Hull Vs Flat bottom Speed

    Alumacraft and Lone Star semi Vs were popular in my boating circles back in the '50-60 time line. They had rounded chines whereby flat bottomed, blunt nosed aluminum boats classified as John Boats were flat bottomed the complete length with a rise at the bow and hard chines. While Lone Star...

    Crestliner seat removal

    I have a 2002 1750 Fish Hawk and removed some floor panels to get at the hardware under the deck. My OEM carpet covered deck is held in place with Phillips #2 screws hiding in the carpet near the corners of the panels.
