I agree with 25 plus knots being the best cruise speed in B25. That is where I normally cruise at unless the weather is too snotty. Regarding the engine ventilating - it sounds like it is only just a little too high, so perhaps some prop work to make the prop work in at this higher level would be th...

Sam's Marine in Fort Lauderdale has the fuzzy stuff and the plastic channel side stuff.
However note they are really a vintage Hatteras supplier bought the above from them and it does fit the Bertrams.

Got some epoxy and other fiberglassing supplies form Raka a few days ago. Seems fine to work with, but can't vouch for much else at this stage as just started to use it yesterday. So far i am ok with it and would buy again if needed

Michael

Raising the top will be expensive, especially as I assume your windows would have to be replaced (unless you plan to raise the cap as well). If it were me wanting to go this route, consider removing top and windows and adding a small tower which could be built to desired height and incorporate a hel...

What is voltage across coil when engine running at say idle, then at 1500rpm? Think it should be less than 10 volts.
When engine dies is coil hot to the touch? If so probably voltage to coil is too high

Michael

Thanks.Now that you have mentioned the number of 44, I feel like I have heard that before.

Michael

Anybody out there know how many were made? I do not think it was many, probably less than the supposedly 99 20' Sportsmans.
Rocket, since you have one, do you know?
Thanks

Michael

Either vapour lock or an ignition component that is gettign hot and breaking down unitl it cools off.

Michael

Originally 31000 customers without power, down to about 6000 now. As population is about 65,000 that probably means about 80% originally lost power. Recovery is way better than prior hurricanes. I was back on line in under 30 hours.

Michael

I am also in Bermuda. I haven't heard from JJ myself. Pretty sure if anything happened I would have heard by now.
My B31, B25 and B20 all survived just fine. In fact I was out on the 31 yesterday

Michael

Here is the spec sheet for the B25. Given that you plan to only hang a 225hp outboard on it, I suspect your total weight will be less than all the option here

The clicking could be a rocker arm that has pulled the stud due to a sticky valve. I would pull rocker covers and start engine and observe the valves to see if they are all operating/not stuck. If this, a pretty easy fix.

Michael

Check your ground line?

Michael

The awlgrip coverage of 210sq ft is at the dry film thickness, which is usually about 3 coats, not the coverage of one coat. So it is my opinion that one gallon should be more than enough to paint the hull sides of a B31. I painted mine with Imron, bought a gallon and still have lots left over, and ...

Michael

Think you will find that the bug will disintregrate in short order, leaving a bit of a small crater where it once was. This will not be visible from 15' As for runs, as the Capt has said, Awlgrip not really repairable. One of the reasos I now use Imron. I find spraying Awlgrip tough as it is soo run...

Michael

I say a carb problem. Possibly water, dirt or sludge in bowl slopping around and partially clogging jets. Or maybe a weak accererator pump

Lewmar concept 1 on the B31
Lewmar 700 on the B25

Michael

Mark,
Mine has the molded in vents on the bow as well. this one, like mine is one of the early ones that still had the curved windshield. Mine is a 62.
If yours is newer and /or has the squared off windshield, perhaps they did away with the molding for the vents.
Hatch looks the same as mine to.

Michael

Tommy,
Pretty sure I got my "20" emblems from High Tide MArine. Mine are stainless.

Michael

To expand on what Navtech said. Try everything that should move and see what does and what doesn't. throttle, tilt, swivel bracket, thumbscrews etc. Check oil in lower unit. It most or all things move, then probably a carb clean, clean points, new impeller, fresh gear oil and a lube of all moving pa...

Michael

Mikey,
The pulls I installed I think are made by Seadog or at least very similar to them. see link below.

Michael

All, Yesterday I took some new pictures to show you what I believe are the distinguishing features of a genuine Sportsman, not a modified hull that looks like a Sportsman. Hope these help and are more useful than the ones I posted a while back when the boat was a work in progress. http://s1225.photo...

Michael

Mikey,
I removed the hatch pulls and installed adjustable twist lock pulls. For the other end I fabricated an adjustable aluminum catch that hooks under the lip. Made it adjustable so I could ensure a tight fit with no rattle.
Other option is to buy a bigger stereo...

Michael

Bump for Dug, and anyone lese that is interested

Michael

Dug, The console if original, has been heavily modified. Where console attaches to floor, the original flange on the console was recessed into the floor, not raised like this one. Should be no raised area forward of the wheel, and there was a door to close off the space under the console. Can't see ...

Michael

Not original. Does anyone have a picture of the aft deck of the engine box if still there?

Michael

Not sure that it is a real sportsman. Center console is not original, forward casting/deck area is higher than original. Can't see engine bay area and aft deck to see if they are Sportsman designb.

Michael

Beginning of this thread has Sportsman pictures.

Michael

I think the easiest identifying factor is the 2 storage boxes on the rear deck, just above the engine. Also the engine box has "wings" which extend out to almost the full width of the cockpit Also forward there is a raised area/casting deck forward of the center console. I am pretty sure I have post...

Michael

I understand 99 were made....

Michael

I know where there are 6 genuine 20' Sportsman's, but do not think any for sale. So there are more than 6 out there for sure, but not many more.

Michael

My view on this plate is that the number is 206 848.

The 20 refers to the size, the 6 refers to the style, much like the 31's. My 20 Sportsman starts out as 204.

the 848 is the hull number.

Michael

Cam,
The engine bay is so long because all these B20's originally came powered with a straight 6 engine, which is much longer than a V configured engine of comparable horsepower.

Michael

I own both - the 11 is much better than the 9, and probably costs about the same.

Michael

Have never insured any boat I own, and I work for an insurance company and it is still too expensive even with a staff discount. I agree it is a rip off especially if you maintain your boat well, check it often, especially in poor weather conditions, are boat savy etc etc. Never bought a boat I coul...

Michael

A sudden stop is normally ignition related. A gradual slow down to stop is normally fuel related

Michael

Ian, I am like you and like to keep bilge water to a minmum. To me the problem with attaching the pump to the boat, presumably under the engine makes it difficult to service or replace.It is also raised up by the thickness of the pad that you put there. So on my B20 and B25 (Which has a single engin...

Michael

Ian,
Who makes that seat? I am quite interested in that. I was thinking of making something very similar. Any measurements?

Michael

I believe both the 25 and 31 versions are the same. I have both boats and both are the style where the complete teardrop top comes off to access the bulbs

Michael

Or there is:
Sea Swallows
Musty Crussel

Michael

Then there is:

Inner Peace
Cunning Stunt
Liquor box
Snatch

Michael

Wrong sender, ie could be one for dual stations and you may only have one gauge. Or could be wrong sender for the gauge being used Faulty gauge?
I agree with others, confirm actual temp with IR heat gun

Michael

Mike O - thank for the links, as I do not live in the USA, this will be a help. I will be in South Florida in early Jan on my way back from BVI and will look for them then. Mikey thanks for the offer. My boat is a 1970, and I do not know the length just yet as windowns not apart. Too long is not a p...

Michael

Thanks for tips - does not look like this is going to be easy. Yes all my bolts are corroded and "welded" to the frames. Wonder if I should just try to cut them out and removed outer frame that way. Where can I get new T bolts in SS that will fit the track?
Michael

Michael

Hello,
looking for advise/tips on the best way to seperate the frames and remove the curved plexiglass. Ideally I would like to remove the plexi in one piece so as to use as a template to make up new ones.
Thanks.
michael

Michael

Frank.
I do not keep track, if I did it would be too depressing. Plus a have several boats and use more than a few each week, so keeping track, if I ever wanted to, would take some effort.

Michael

I wish it were that cheap here, I am more in the $8.50 range

Michael

Guys, I got both the nylon strip the glass rides on and the felt side strips from Sam's Marine in Fort L. You must know up front that they are a vintage Hatterass supplier. Sam's marine 3838 SW 30th Ave Fort Lauderdale 33312 954 585 8933 I have th parts numbers for the above at home which I can get ...

Michael

If I had a inboard B25, that would be my prefered power option. I am a big single engine fan in smaller boats. Putting the bulk of the weight in the central location seems to be best for these boats. And whilst outdrives are not everybody's favourite, they do provide shallow water operation and grea...

Michael

I am with Gert on this one, this looked like a very nice late model B31. For the type of rebuild being done here, surely there was a basket case B31 out there that would have better suited for this style of rebuild. I hav enothing against the rebuild, just the starting platform being used. I would h...
