Same prep. Rough up the surface, clean well, go to work.

MAS makes a great epoxy product. I'm guessing that most others are also fine.

You don't need to gelcoat. The inside of your boat is uncoated fiberglass. No harm in it being wet. Paint won't hurt it, antifouling paint included.

mike ohlstein

Basic rule of thumb. Epoxy is an adhesive. Polyester is not an adhesive. Poured monolithically, they are roughly equal in strength. Polyester resin is much less expensive than epoxy. That's why boat builders use it. I'm not suggesting that polyester resin isn't sticky. It is. So is chewing gum, but ...

A new truck is 70K. This one will cost 50K (including purchase price) over the next 10 or 12 years and still be worth 10K.

mike ohlstein

Any suggestions on a truck that can tow at least 7500# and 4 full size doors and at least a 6.5' bed? My last truck was a F-150 I loved it. We have twin girls at 4, so a easy to access back seat is a must and I keep my trucks for a long time. https://www.ebay.com/itm/2000-Ford-F-250/143905460315?ha...

The slides are rated for 265lbs the cooler dry weighs 23 pounds it’s only a tundra 45. 10 pound bag of ice and 24 beers is 24 pounds around 57lbs total.

Nobody knows what five quarter is?

Wheel suggestions: 20X21 4 20X22 3 20X23 3 21X20 4 21X21 3 21X22 3 Each will give a slightly different wake pattern when trolling, which will also change with how the boat is sitting in the water at any given time. I've personally caught more fish with the 20X21 4 blade props than with any other. No...

I've had great luck with 21' poles, no wires. Let 'em flex. Makes your presentation more lifelike.

Four seats plus a luggage 'compartment'. Two sets of flight controls. Pretty nimble for a somewhat heavy aircraft.

My nephew tells me that plane is fast and agile. I guess you feel the need for speed.

Exactly......

I had a deposit on a Deb but it didn't pass inspection.

Strong work

It's going to cost more to restore than it would cost to buy a finished boat. Tell him you'll take it off his hands if he pays to have it delivered to you.....

Seriously.

Turning did him in, I understand that. But what does one do when they know they are not going to make it through the next one. Obviously that decision should be made before committing to an inlet, but at some point things can go from doable to not gonna happen or just a rogue wave. I do not run inl...

Perhaps reading this particular article from Captain Pat will help.

The purpose of those roughly triangular hawseholes is to set the direction of pull of the stern lines in relation to the cleats. This causes the force on the aft cleats (and more importantly, their hardware) to be in shear, not tension. Since we're now talking about shear strength, the cross section...

I have only used smaller chargers, but have boiled some ATV batteries with Noco. That's why I switched to CTEK. I have one that is a lithium battery charger (I use them with electric reels) and two that have been in service for several years in the shed.

mike ohlstein

Agree on Noco, but I am using CTEK smart chargers on my ATV and home generator with no problems. I do have them on timers...... I run them every other day for 12 hours.

mike ohlstein

I used 1.5" Soundown, and along with the glue I used 1 5/8" screws with fender washers to screw into the plywood that's under the top of the engine boxes.

Maybe I'll get some pictures this weekend.

mike ohlstein

Is it set up direct drive? Just wondering if I know the boat.....

mike ohlstein

I might have some too....

mike ohlstein

Post a link to the dead thread

mike ohlstein

I believe that the boat was manufactured prior to the Title Era. You'll likely have to have the police check the hull ID to see if it's reported stolen, and then register it as a salvage. A bit of a hassle but doable.

Gas is great for Howdy Boating.

I used to get .8 mpg at 18 knots. Better at trolling speed, much worse at ramming speed.

Please please please.... don't make any critical structural repairs with polyester. Polyester is NOT and adhesive. Epoxy is.

devinfox wrote:Damn you work fast! Are you using poly resin for those repairs? Keep it up!

I hope not....

Polyester is plenty strong monolithicaly, but it's a poor adhesive at best. Repair work that needs to stick to something (as most repairs do) should always be done with epoxy.

mike ohlstein

Take it easy there buddy.

If you tell people that we're acutally a bunch of nice people, we'll never be able to drive them away......

I think you're ok with that. If you have good pressure at 1500 rpm, and just about any pressure at 800 rpm, you're fine. Especially when the oil is warm.

Wild guess..... Transmission is locking instead of slipping. Put it in gear, it kills the engine.
