    Re-powering - your thoughts

    I am going to re-power my old 1976, Aquasport 24' Family Fisherman. It has a vintage 1984 Yamaha 200 hp on it now and has been very reliable and plenty motor for the boat.

    Switch broke

    Hi forum members, the key switch on my older Yamaha 703 control box broke up when the plastic failed. I never thought there could be so many little parts and springs in such a small space as the keyhole. The switch has 3 positions, Off, On, Start. The electric choke solenoid is operated with a...

    Plug wires

I pushed them on tight and installed cable ties around the boots and plugs to keep them snug. My question is, can the plug wires be replaced without replacing the coils? I...

    Souped-up Yamaha 150

    Hey guys, did Yamaha ever market a special edition 150 HP with a 20in shaft for Bass boats that was really more than 150hp? A guy wants to sell me a used powerhead off such a motor. I have not looked at the motor yet because I want to check out the info. He claims it's more like a 200hp and was...

    Need decal parts

    I'm putting a 1976 Mercury 9.8 back together and the decals are badly worn. Does anyone know where new ones can be purchased on the internet for this model year? Most of the sights I've visited only have decals for motors from the '50s. Thanks

    Garmin/Lowrance fishfinder

    I am replacing my Hummingbird 300tx (Junk) with either a Garmin 240 Blue or a Lowrance X-91. They seem to fit my budget. Does anyone have experience with these units and/or recommendations.

    I'm using a Merc 9.9 as a kicker/trolling motor and it moves my 24' boat at 6mph or so wide open. It has the standard 2 plade prop. Can I change to a 3 blade like sailboaters use and improve the speed. There is no tach on the Merc but the RPMs sound low. What is the rule of pitch/dia if I can...

    Yamaha question

    Need feedback from a Yamaha guru. I plan to replace my '84 200hp Yamaha with a new unit and have been quoted prices. I can get a 225 ox6 or a 200 hpdi for relatively the same price. Is there pro/con opinions on ox6 opposed to hpdi and 225 to 200hp? My old 24' Aquasport has performed great with...

    Which outboard to choose

    I am now running a 1984 200hp Yamaha and I run it a lot. It came to me with a used rig purchased in 1993 and the previous owner had it rebuilt once. Although it is still performing great, I feel I'm on borrowed time. When I repower, which brand outboard would be the "Preferred" one? I have no...
