SOURCE: Why are Aluminum Fishing Boats the Best Fishing Boats?

A timber boat is high maintenance. Trust me, I've had quite a few. You're always sanding timber, varnishing timber, repairing timber and lots more. Now if you're happy to be doing that then that's great, but recognize that's the price you pay for a great looking timber fishing boat. And a timber boat is often heavy, and will not last well, particularly if you aren't as diligent with your maintenance as you could be. And they puncture easily when you hit something, as I did last week. But if you're not an enthusiast for working on boats then timber isn't your best choice. What you want in a fishing boat is this. It needs to be tough. It needs to be low maintenance. It needs to be puncture resistant. It needs to last forever without spending hours working on it. It needs to be easily repairable. And it needs to be cost effective. For me the best choice fishing boat is an aluminum fishing boat. Aluminum has properties which make it the perfect material for building fishing boats. It is very light and strong for it's weight, and can be easily welded, so is ideal for both building and repairing. It is extremely long lasting, and is very resistant to puncture. Now of course that doesn't mean it can't be damaged, as it can. But you need to hit it pretty hard to do some serious damage. And if you did that to a timber or fiberglass boat it will be very seriously damaged. And an aluminum boat may just dent, rather than fracture, so you can head right back home with nothing more to show than a dent, instead of possibly be the subject of a rescue from a sinking boat. And it lasts forever if treated right. If you get a great aluminum fishing boat and treat it well you may well find yourself leaving it to your kids. Because aluminum boats are light for their strength they often need a smaller engine, and the engine is probably the highest cost item. A smaller engine costs less, and uses less fuel. And with a smaller engine they are also lighter and easier to handle. And they require little maintenance. Make sure you hose your boat down after a day out, especially in saltwater, and if you drop a lead sinker make sure you pick it up, as it's not great to leave any other metal in contact with aluminum, otherwise you don't need to do too much maintenance at all. More fishing time. And because aluminum boats last so well they also retain their resale value well. I bought a used aluminum fishing boat 2 years ago and it is currently worth a little more than I paid for it. So there's plenty of good reasons to buy an aluminum fishing boat. Unfortunately they aren't cheap if you want to buy a new boat, but for the same reasons I've mentioned above, it's way better to buy a used aluminum boat, as a used boat is usually much cheaper than a new one, and retains it value well. I would never buy a new aluminum boat. So grab yourself a great used aluminum fishing boat and get fishing this summer, it's the best way to get on the water.

I have a maintainance manual for this engine (I have the same one) with pages of wiring diagrams. What specific system/area are you interested in, I could scan in the page(s) and email them to you.

SOURCE: No depth reading while on plane.

Depending on your transducer type, you may have a liquid filled type that simply needs refilling. If this is the case check for leaks and get it redone. If not it could be transducer placement or cavitation under the hull.

Mercury 90 hp Optimax problem


Since it's an Optimax, I'm going to have to defer to an authorized Merc service station. Barring that sounds like a fuel problem, try cleaning with some Seafoam or the Merc equivalent. I'm guessing this after is sat all winter with no love.

Y does my 2003 mercury outboard 200 efi take so long to get by 21 foot pro craft out on a plane it is really slow


Check the size and pitch of the prop. By reducing the pitch you will get better hole shot out of the water ,but my be lose a little top end speed. This will be stamped or cast into the prop eg: 15x21 which stands for 15 inch diameter by 21 inches pitch.

Boat does not plane


you could try a lower pitched prop.2" would up the revs by 400 revs.,which would up the revs ,but give you more low down thrust,and/or tucking the motor under more[if you have electric trim/tilt].thats a big boat and fair bit of weight for a 40hp..my 40hp merc is on a 13ft saracen,and with two of us it takes a while to get gooing.so i bought a ProPulse prop,with adjustable pitch.been god to try different pitches
