Replies: 4

Berk pump is not all that sea worthy for open-water use. Proper lubrication in a constantly-submerged operation is going to be a pain. Unlike a regular drive, the shaft seal has zero redundancy, and operates under substantial pressure (especially under throttle-closed, high hull speed) 1) it would t...

Re: BEST PROP FOR SPEED?

Where is the best place to go to find info on best prop to use on outboard. Have merc 20 with original two blade prop. Some say a three blade would be better for more speed. Everyone tells a different tale. Allot will depend on the hull as far as selection of the proper pitch. One thing is a true c...

Caber-Feidh, what is your home port? I boat a lake on the Canadian border myself called Kabetogama. Up here the days are in the 50's and most nights are nearing low 30's now. And If I may ask tell me a little about your screen name. Is it latin, what does it mean? UPSPirate how much further south d...

That site gets "5-flying-fickled-epoxy-rollers-of-doom" rating. Not sure about their product, looks just like RAKA's stuff, a bit cheaper. Likely more than acceptable. But wow, what a site, that's what you get with the generic free wysiwyg from your hosting company. Well, at least you know they aren...

Epoxy the parts you don't want to scrape and recoat later. Paint looks better, but doesn't hold out over the long term (it does take UV better though). Varnish is great protection, but only holds out a couple of years. Not sure about garage floor coating. As a lifelong victim of Murphy's Law I am af...

Great looking boat!

Loud is good... real good!


In my book, any launch that is accompanied by an escort boat, and not a rescue boat is an unmitigated success.

Spudfyre, I'm with Steve, on this one. I used boat nails though. Two additional reasons. Without fasteners, you run the risk of bumping the frame before the epoxy cures. second you can take the frame off the table immediately and go on to the next one. As an engineer, I've always wondered why many ...

Topic: Cavitation at higher elevations? Need help.

It's the altitude, and lack of air for the motor, not cavitation. For example, at 6,500 feet there is about a 25% loss in shaft HP for a normally aspirated engine, not to mention the slobbering rich condition of the fuel mix unless you rejetted. Efi may/may not compensate properly. Unless the system...

BS 1088 requires the face veneers (each one) to be a minimum of 1/8 of the total panel's thickness. In 6mm 3-ply the faces each have to be .75mm.

It is common (here at least) to find thick center cores with thin face veneers.[/url]

On most jet setups we skip the thermostat completely. It's usually just another thing to break (usually by sticking shut, and cooking the engine) Automotive 'stats are not designed to be left unsubmerged, but in a boat app they will be, in comes a little corrosion, and there goes the motor when it s...

What type of thermostat are you planning? From the look of the plumbing left in your pix it appears that it was not setup with a 4-port. Not uncommon to just see a splitter on top of the manifolds on that old stuff. You don't need any engine circulation pump with the proper sea pump, adding one is j...

I agree 100% with V-Driver, Fuller's of even well crushed kitty litter will take allot of it out. Just dumped into the hull, and changed regularly it will get allot of it. Follow the clay up with an acetone wash before bonding. (or better yet, toluene but wear proper haz-mat protection with that nas...

I have had excellent luck with Piranha! they will trade blades as long as you haven't damaged them. pretty easy to put new blades on, and a spare set is a heck of a lot easier to carry than a whole prop.

Honda has their own strange final drive ratio, just to add some excitement to the whole mess. Stock (USA version) it came with 11.25x12, Honda pn 58130-ZV5-000ZA or 11.5x10 (58130-ZV5-850ZA) Both are about 200$ here in the U.S. The full range of what honda has mounted on them for various stock apps ...
