    88 SPL Charing Issue?

    I have a 1995 88 SPL. Normally my volt gauge will read anywhere from 13-16 volts with the engine running. Today I noticed the guage read 12 with the engine running up to 5000 RPM and also read 12 with the engine off. It's acting exactly like it did a couple of months ago when my rectifier...

    88 SPL WOT - Prop?

    I've got a 17 foot Aquasport with a 1995 88 SPL that I am only able to get up to 5200 RPMs at WOT. RPMs verified on two tachs (TinyTach and dash tach). I'm pretty confident that the tachs are accurate. 5200 RPM puts my speed at 38mph (GPS). I'm running a 3 blade 15 3/4 x 15 prop. I've read...

    88 SPL - Tiny Tach

    I have a 1995 88 SPL. I bought a Tiny Tach a couple of weeks ago in order to trouble shoot some funky readings I'm getting on my regular tachometer. The first unit they sent wouldn't go over 2500 RPMs. I called Tiny Tach and told them about the problem. They guy said there was a bad batch...

    Do I need a different prop?

    At WOT I'm running about 7000 RPMs. I have a 17ft aquasport center console (1500lbs) with a 1995 Johnson 88 SPL. Range is 4500-5500 at WOT. The current prop is a 3 blade 15 3/4 x 15. Do I need a different pitch to get me down to 5500 at WOT ? Thanks

    Fuel Primer Solenoid Broken

    While rebuilding the carbs on my 1995 88 SPL I broke one of the small nipples on the primer solenoid. Does anyone know if I can buy just the plate assembly with the nipple, or do I have to buy a whole new unit? Also, could someone help me locate the parts here on iboats? I haven't quite...

    Replacement Rectifier (Two Yellow Wires)

    Got a replacement rectifier for 1995 88 SPL in the mail today. It's got two yellow wires instead of one yellow and one yellow/gray. Any ideas on how to hook it up? Do I just guess? Will I blow a diode if I don't guess correctly the first time? Thanks

    Which Carb Kit?

    Hi all, Hoping someone can help me figure out which carb kit I need. I just got a boat with a 1995 Johnson 88 SPL (oil injected) on it. It doesn't idle well at all so I'd like to get into the carbs (it sat for 3 years before I bought it). I don't have a manual yet (on order) so I'm having a...

    Small Rectifier Test Results

    Hi all, New here and need a little help interpreting my "Small Rectifier Test" results (thanks, Joe Reeves!). I just bought a 1995 Aquasport 175 with a 1995 Johnson 88 SPL. Tach and charging system aren't working. The tach does "zero" out when the ignition is on. The previous owner was...
