When you go to install the antenna bolts overdrill the aluminum holes and install a flanged plastic bushing. The outrigger manufacturers use this technique to "insulate" the stainless hardware from the aluminum tubing so they can be taken apart. I did this with my hardtop when I refinished it...

There is no good way to work on the fuel fills. I cut a 12" square out on the flat part (flat to make repair easier). Replace all the hoses and install a new Perko fuel fill with bushing (included with new fill) to deflect water away from the fill. On the Islander the forward tank was...

I did my islander tanks. Not the same but common problems addressed. Good luck! https://www.greatgrady.com/threads/268-islander-fuel-tank-replacement.36637/

Internet fraud is big business. You have the laundry list of things to watch for! You can't be careful enough. It's still possible to buy safely. I have seen a few GG members burned by scammers (last month!). Not always expensive stuff either. They expect the GG admin to protect them. It...

Yes just try it - with the right tools and prep. You get one shot before you strip it and make a project out of it. And if it comes off 1st. try great! That's what we expect. Good luck!

As Dennis said "good downward pressure". You only really get one shot with a power tool. Hand tools give you better control. If you spin it you are done! It's a real mess from there.on.

Are there nuts on the back side? Do not use a screw gun or impact driver at least initially. Go to Lowes or Home Depot and get new properly sized bits. You are more at risk of stripping the Philips head than breaking it off. Use plenty of PB blaster. Try to slightly tighten and loosen to see if...

Read SkunkBoat's post above. He has part numbers and sources in there.

Be careful buying off Great Grady forum. Fraudsters will likely Private Message you with an incredible deal "too good to be true and probably is!". I wouldn't buy unless it's a local sale that you can touch and see. I have had good success with eBay. You still need to be careful. When I see...

With moisture levels at 30% and the previous survey recommending further investigation be done I would be concerned. Call GW customer service and ask why the transom and stringer materials were used. Do a Google search: "how much moisture in boat transom". 10%-15% is normal. 20%-30% indicates...

Fuel tank's are a replaceable maintenance item. You can't make them last forever. 25 years is a reasonable goal. At that point you just don't know. It always pays to use ethanol free gasoline. It's far better for your engines. The tanks will take care of themselfs.

Double sided tape is ok to hold things in place while the 3M4200 cures but it's what failed on you and why would you use it to glue it back up!

Painting fuel tanks even with epoxy doesn't always protect the tank. Some tank builders will tell you not to paint them at all. The reason is the paint doesn't stick well to aluminum. Zinc chromate is a toxic paint that does an excellent job of preparing the tank. For my tower that was...

AI seems to think the oil can go bad! AI Overview Crystals or sludge in a fresh container of Yamalube 2-stroke oil usually indicates the oil has gone bad due to contamination, moisture, or age, and it should not be used. Check your oil supply, and if you see any particles, separation, or it...

Change all the fuel hoses out. As the hose ages the inner wall can separate. The suction from the engine fuel pump can collapse the inner wall and block fuel flow. Have seen this several times. But you replaced all the hoses 2 years ago. May be clogged pickup tube strainer. Again new tanks so I...

Check the other containers. I would call Domo and Yamaha customer service. Is this coming out of the Yamaha bottle or in your oil tank? AI Overview Yamalube oil showing crystals, separation, or sludge is often carbonized, unburned oil and fuel mixture from the exhaust, especially after long...

Every container like that? Take it back!

You should fill filters with fuel before putting the up. Make sure o-ring which should have been replaced is in place on engine filter. Replace fuel bulb-only good for a few years. May be fuel lines.

Be interesting to ask GW what the life expectancy of their hulls were designed for by model year. What is a reasonable "life"? A friend of mine said: "Fiberglass hull boat can last indefinitely." That is true if built properly and the core materials are protected through the years.
