This would be a good application for an aluminum screw.McMaster-Carr offers aluminum sheet metal screws. m.w.

You may want to check that the cam follower bushing is not worn or missing as this will not allow butterfly to fully open. M.W.

Test every section of your circuit for voltage drop to find the bad connection. Positive battery post to lug then to switch and so on until you end up at the neg. post on battery.#2 wire is not necessary.m.w.

I suspect that the flywheel may have rotated during installation due to the crankshaft being lubricated.When torqueing the new flywheel it would be wise to immobilize the flywheel. Your motor being the lightest 25 is very sought after by flats fishermen and will fetch a good price if you ever...

A voltage drop test will show what part of the circuit has excess resistance.Should total less than 1 volt.You may need to make a jumper to extend the leads of your multimeter.

I would suspect short.HT leads or bad plug.You may try choking or spraying premix directly into carb if rpms increase you can assume not electrical. m.w.

"mercosil" will be printed on the starboard cylinder if not chrome bore both very hard material and may not show damage even if piston is toast.Best to remove exhaust cover by partially disassembling lower cowl as well remove inspection covers on transfer ports to see if piston is scored.Parts...

My Yamaha dealer will let me buy props and return them in perfect condition so why wouldn't yours?Did you buy the motor there?My friend has a F25 on 15' rivetted boat with wood floors and with two 200lb men will see 25mph at wot without hitting the rev limiter(no tach) with a Yamaha 9 7/8x10 1/2...

Sinkingfast is correct wot mixture is a function of main jet size,however only two sizes were offered #92 for the 2.5 and 3hp models #94 for the 3.3hp.Needle position was the only adjustment for elevation.The jetting chart I have does not cover 2002 Tohatsus so it is possible other sizes are...

Sam your motor is equipped with a variable venturi carb that utilizes a tapered needle in the main jet.The needle has multiple grooves that hold it in the throttle/slide and can be positioned higher or lower by means of an e-clip to adjust for altitude.I suspect you need to raise the...

I believe your motor to be a mid eighties "international model" as per Crowley Marine website.m.w.

What you want is a breakaway plate which is a jackplate that pivots at the top when you hit an obstacle.A proper breakaway plate should have a safety strap or some type mechanism limiting its travel.I have hit a log at speed without power-trim and the lower unit swung up nearly vertical breaking...

No need for washer as long as nut is only contacting inner race of bearing.Chad I noticed you have a 89 Montero.I own a 89 ram 50(Mitsubishi mighty max) 4x4 that was supposed to be a temporary vehicle but has proved to be very reliable despite having a complicated emission controlled carb.How...

Great thread on The hull truth about guys building their own 12v lithium batteries.Lipo4 and Lito cells can be fully discharged with very little voltage loss,charge quickly and will last 20 000 cycles.Incredible energy/weight.

If this is a Commander control chances are the key switch is broken or has been disconnected.The stop circuit wire(blk/yel)will be found at the lanyard kill switch and then go to the key switch(if these wires are not color coded it will be the one not grounded when key is on).Test the key...
