    2001 200 XL No smoke

    I have a new-to-me 2001 200 carb engine that was just rigged on my boat. It replaces an old black max that had the oil injection removed and was running premix. I fired the new motor for the first time tonight. My neighbor jokingly asked where the smoke was. He was right. Little to no smoke...

    Inboard with prop pocket to outboard?

    Im almost ready to splash my Hydra Sport rebuild and I’m already considering my next project. Has anyone ever converted an inboard single screw with prop pocket to an outboard on a bracket? I’m looking at a 24 Topaz center console. I posted on the Facebook Topaz page and was pretty much accused...

    78-79 hydra sport transom and stringers

    I noticed last year when installing a new transducer that my transom was wet. A couple weeks ago I started into demo. This is a "Kevlar 49" hull. The hull itself appears to be very solid. The deck is also very solid other than some stress cracks at the corners of hatch covers and access...

    Bow Rail Replacement

    My bow rail was hit by something (prior to me owning it) and has a bend that has always annoyed me. I am considering taking it off and trying to straighten it. However, I found that it has lock nuts which are not accessible without removing the rub rail and separating the cap - not something I...

    78-9 Hydra Sport 21cc transom

    Not what I was hoping to do this winter, but here I am. I had noticed last spring that the transom was wet and the bottom of the stringers was questionable where they tab in. Drilled out the two scuppers and found they had rotted out. Sooo...I pulled a section of deck and transom to allow me to...

    Blackmax 200 spraying fuel

    I was doing a compression test this weekend as I am trying to determine why I am not reaching max WOT. I recently downsized my prop with very little impact - see the post in the prop section. Anyway, I had the cowl off the engine warming it up and noticed it was spraying fuel from what I...

    New 4 blade Turning Point Prop...meh

    So after figuring out part of my previous issue was a bad tach (replaced), I was only hitting about 4600 at WOT for about 35 mph. 86 200 blackmax on a 21' Kevlar Hydrasport. Old prop was a stainless merc 23p 3 blade. Went to a 19p aluminum 4 blade. I only picked up about 200 rpm and lost 2-3...

    Weak starter solenoid?

    Lately I have had several instances where when I turn the key I get a "whirrrrr" but the engine is not turning over. It will do it a few times and then decide to catch. It seems intermittent and happens hot or cold. Is my solenoid going? It's a mid 80's 200 Blackmax.

    Best 2 stroke oil for less smoke?

    I have a Blackmax 200 with the oil injection removed. I'm running 50:1 Quicksilver 2 stroke oil as a premix. Flipping around Youtube the other day I found a video of a guy who swears by Amsoil and was showing a reduced amount of smoke. So...if I'm at idle or trolling speed, +/- 2-3 mph, what...

    Blackmax Tachometer Poles vs. Pulses???

    Okay, I am either real close to getting this nailed down or real close to losing my mind. Not sure which. Long story short, I have reason to believe the tach readings on my boat are wrong. It is an older Teleflex. Settings go from 1 to 6P. From what I understand, my Blackmax 200 is a 12...

    Blackmax 200 - Prop issues or something else?

    Last summer I picked up an old hydra sport 21 center console with the kevlar hull and a late '80s blackmax 200. It is a bit of a frankenstein motor as we intended to repower almost immediately (haven't gotten there yet). I believe the lower is off of a 150 or 175 and is geared accordingly...

    1987 Blackmax 200 smokes (more than usual), dies at idle

    So the boat ran great on the muffs and when we launched about a month ago. We installed a new voltage regulator/rectifier combo this year and it seemed to run smoother than last year and with less smoke. It had 1/4 tank of fuel and I added another 30 gallons fresh to bring it up to a little...

    87 Blackmax 200 New Regulator/Rectifier Install

    At one point last summer my charging volts were bouncing around between 12-16v. It did not seem to make a lot of difference what speed the engine was running. I also had the tach showing between 5-6000 but I don't really believe it. This is a new to me old boat. A 21' Hydra Sport center...

    Trouble Bleeding Blackmax Trim

    Last fall I lost the trim motor on my '87 Blackmax 200. It had a two wire motor with relays installed (not sure if this was original or not). I replaced the motor with a new Arco unit and got it hooked up. I raised the trim all the way up/out with no weight on it to verify the motor worked...

    Bumpy ride after rebuild

    Late this summer I picked up a small center console and trailer. I had to replace the trailer because the one it came with had no title and dealing with that in Maryland is a nightmare from what I learned. Anyway, I bought a used one that was supposedly road ready...right. It towed great on...

    1987 200 Black Max Issues - Overcharging, RPMS, and Trim Motor

    So we got the boat launched on Friday. She runs like a champ but certainly different than what I was used to. I was used to IOs with power steering. My arms are getting a workout! I did notice a few issues I wanted to run by you guys: 1. The voltmeter is reading 16+ most of the time...

    1987 200 Black Max powerhead on 150 lower

    I recently purchased an old Hydra-Sport 21' center console (kevlar) with a 1987 Black Max 200. I understand that the lower was replaced with the lower from a 150. From my research I have found that the ratios were different. The 200 was 1.87:1 and the 150 was 2:1. The motor has a 23p prop...

    New (Old) Boat

    Hey guys, long time, no see. I used to spend a lot of time on here and then had two kids...you know the story. Anyway, my oldest is almost four and I just bought a new boat so we can do some fishing. It's a 1978 Hydra-Sport 21' center console (kevlar model) with an 87 Black Max 200. I hear...

    Mounting a new head - holes don't line up - SOLVED

    Hey guys, this may sound like a really dumb question, but here is my dilemma today... The PO cleaned the bowl of the old toilet with something that ate the finish off - I'm pretty sure it was porcelain, so I can't imagine what they used. Anyway, the base metal is rusting away. In addition...

    New plugs causing engines to run hotter???

    Hey guys, did new risers and manifolds and new circ pumps this year. Checked impellers and both were in good condition - still full vanes and no set. My twins both have always run about 165-168. I replaced the plugs with the factory spec champion plugs which were the same plugs I pulled out...
