After installing the new rectifier you can do the same test which made you think the alternator is bad. If it still behaves the same the old rectifier was ok. What you told there is written in the documentation looks to me it is ok to use the outboard without battery connected.

What was the original top skin made of? Any oriented or just chopped fibers? Top skin is thicker just for possible impacts. If the new foam is stronger than the old then skin could be thicker too. With biax resin content will be lower than with just CSM and density higher. So 6 mm of that would...

Have you seen this? http://www.hotvac.com/default.aspx They do a similar thing commercially.

How do you estimate true wind direction? Does the heeling force from the sail feel the same on both tacks? If not perhaps you are not pointing as high on both tacks.

Spectra has really poor bond to resins. In armor use that can be an advantage as fibers are able to slide inside the matrix dividing impact energy to larger area. In other uses that kind of action is not a sign of good laminate.

Iges comes out of Catia easily. Just have to learn Rhino then. On UliTank is Z-axis always normal to waterplane? BR: heikki

Hello, I haven't created an offset table from the model as I do not know how to create it automaticly. Ulilines 3.3 seem to be making about 3000 points and manually measuring and infeeding that amount of data to a file is a big job for a hobby. The points given by Ulilines I can feed to...

The UliTank thread is expired so I ask here. I have a hull shape in CatiaV5 format. How to easiest import it to UliTank? Also how should origin be placed? UliLines 3.3 manual says it places origin to forward end of water line at the level of water. Tested to create hull shape with same...

Recitifier/regulator Most likely the recitifier has a regulating function which limits max charging voltage to a safe level. If motor is run a longer period this could be noticed by measuring battery voltage which should not exceed above mentioned values. The regulating function also explains...

Been there and done that My Yamaha charging circuit on a 6 hp outboard is behaving the same way. Explanation is the charge regulator. Disconnect it and measure directly from AC from coils and you will notice it works. Measure with meter set to AC- voltage. The regulator needs a battery- like...
