Did you own a Shannon sailboat? One of my favorites, so their trawlers should also be nice. David

You could wire the panels all in parallel which would limit shading interaction among the panels. But you have to have a controller that can accept the higher current and a wire gauge big enough to limit the voltage drop. David

Three blowers is quite a lot. Why three? Also the voltage dropping to 11 is a lot. Maybe the wiring is too small or bad connection causing voltage drop. Are you measuring at battery terminals? David

Cruising at 10-11 knots while pulling a heavy dinghy may put the engine in a high stress point. I suspect at 10-11 kts the boat is pushing “the hump” but not over the hump on a clean plane yet. I would either slow down to 8 kts or speed up to more than 12 kts to put the engine in a more...

Years and years ago, I anchored in Mill Creek to the east. Lots of room and quiet. David

What rpm can you attain at wot? You may be overpropped. David

Rotate it, pull the gen head off, send it to Broward Armature for a rebuild. Sounds like your easiest and cheapest option. David

With what little info you have provided so far I would say 10 gauge wire with heavy alligator clips on both ends. David

I have never jump started a pump (what kind?) and don’t understand why you would need to do it. But use a cable, heavy enough to carry the pump motor starting current, roughly 3 times running current, and big enough to keep the voltage drop below 1 volt at that current. Then put alligator clips...

Sure, all you have to is have a prop shop rework the new props so they perform like the old. Probably they will reduce the pitch to match the old. But are your current props right? At wot your engines should rev to a point 50-100 rpm’s more than rated wot power. But you must use accurate rpm’s...

I only keep a small fraction of our savings in the bank. The great majority is in brokerage accounts. I will close on a new to us condo in a few weeks. I sold enough stocks to cover the closing cost this morning. When that clears (takes 1-2 days) I will then EFT it to our bank account. A few...

Did the OP (who has never posted again, we probably scared him away) mean cash folding money or no financing involved. I think he meant the latter, but most of the posts above, assumed the former. This thread was kind of fun to read, but mostly irrelevant. David

I have bought and sold a half dozen or so cruising boats over the years, half for cash and never had a problem. Are you concerned about brokers not taking you seriously? Wow half the homes in my area sell for cash. Cash is king. Are you concerned about getting ripped off? First have a good...

I would leave it on and flush one or twice a week to keep the internals wet and thereby lubricated. David

I just checked out the Rosborough RHIB. Neat boat. David
