Agreed. I’m not able to get the serial #. It’s an oddity.

My buddy works with a guy who is selling his Mercury 250 (Pro XJ Xtreme). I’ve certainly never heard of this motor, nor does Google apparently. So I told my buddy there must be some sort of mistake,...

I have recently acquired a 2014 Nitro Z7, and I would like to add a passenger/port console. They are no longer available from the factory. Black with red flake is preferred as that matches my boat,...

I’m no expert but apparently this is a subject that very few people have any good knowledge about. Zukes are kinda off the radar, for now anyways. Theoretically, one could install the DF200 ECU on a...

Those are some of, if not the powerful and fastest 2 stokes ever made. The DT series always seemed to pack quite a bit more HP than the number on the cowling suggested. Back in the early 90s my uncle...

In my limited experience what have you heard is right. Rugged and reliable, hard to prop and slower top end. I’ve been running a DF 150 for a few months now, and yes it was quite difficult finding...

Yes sir, I would be very happy with 61 miles an hour. However I don’t think that’s a reality with this particular boat/motor and it’s low gear ratio. After trying several props that were available to...

I’m not hitting the Rev limiter with the 26P Scorpion, my analog tachometer is somewhere in the 5950 range WOT fully trimmed up, 55mph. I’ve tried a few other props I have laying around, the 26P...

Yes sir, it’s a 15 1/8” dia 3 blade with some pretty aggressive cupping. I’m still plying the “dial it in” game. I made some adjustments and ran it this evening. Lowered the prop 1 1/4”. (3 3/4 below...

Ok, so the 26” Scorpion is a step in the right direction. Got to run it for a couple hours this evening. Got the boat up to 56mph @ 6000 rpm. Hole shot not to great, so I opened to exhaust ports 100...

The motor doesn’t die. It’s done it to me twice now, only after I’ve been running it up pretty high speeds for over an hour. It’s like the prop just stops turning, really yanks on the transom. I’m...

So this is a strange problem that I’m having intermittently. The motor runs great, perfect compression and good spark to all cylinders. Cranks up as it should. And most of the time it runs fine. But...

The 3 blade 23p” Suzuki 16” diameter factory prop absolutely nailed the rev limiter at WOT after 5 hours of break in. 53 mph top speed. I ordered a 26p Scorpion, will report back on the performance.

Hey there Suzuki folks, As it says in the header I’m re-powering my Nitro Z7 with a Suzuki four stroke 150. Not the SS model, just wasn’t available. Everything that I have read about propping is a...

So... I found a low hours 2006 OptiMaxx (sorry didn’t get the SN) on Facebook marketplace to replace my recently blown 2014 Pro XS opti. Went over to the guys house with a few basic tools, a spark...

Yes sir, will do. Is there any quality difference between the CDI brand and Quicksilver OEM?

Yep. The starboard switch box, which is connected to the port bank of cylinders is getting input, no output. This explains the alarm as this box has the green wire going back to the Lubalert alarm...

Stator resistance test seems be within range. Red to Blue - 3833 Ohm’s. Red/white to blue/white - 3849 Ohm’s. Red to black - 111.6 Ohm’s. Red/white to black - 111.4 ohms. Switch box failure is my...

Thanks Joe. Pulled the harness and jumped the starter, no joy. Weak intermittent spark still. I will ohm out the stator this evening, I don’t have a DVA adapter but since it’s not running don’t think...

SN#OG172120- Running the boat in about 4500 RPMs when the motor lost power, somewhat gradually. So I I mediately shut the motor down. Fast beeping alarm was sounding. Reset ignition, the motor...

Well... the OptiMaxx Pro XS 150 (1B937665) that I purchased on my new boat didn’t last long. Mechanic told me that a direct injector plugged and destroyed one cylinder, the engine is seized. The...

As always, I found great advice on these forums. Thanks for y’all’s guidance. I put a flat edge on the rear portion of the boat, everything was flat. No hook! After a compression test on the 150...

If you don’t mind me asking, do you know what the cause of the hook in the hull was? Did it come off the factory floor like that or something that occurred later? I’ve heard that not fully supporting...

Yes, that is a concern. I have heard about the hull with a hook, and a lot of these models seem to have had it. How do I go about checking for that? I’m assuming that if this boat is running around...

I’m in the process of purchasing said 2014 Nitro Z7. The boat that I’m getting comes with a Mercury OptiMaxx Pro XS 150. The owner says it runs about 59 to 61 miles an hour. What confuses me is that...
