    Converting Tohatsu 5hp to 6hp (4 Stroke) returns disappointing results.

    Sounds like you found the happy spot, great job. How much did the Solas prop cost if you don't mind saying? Also just for one more datapoint to add to my info above; my motor is too long for my boat by a couple of inches.

    BF15D old corroded anode won't come out for replacement

    Why won't it come out, are the screws stuck?

    Honda BF15 dies at 5 minutes at idle

    Also if squeezing the ball makes a difference, then double check all the connections and make sure none are leaking. At idle the pump isn't pumping a whole lot and a small leak could let enough air in to cause a problem, but at higher rpm's the pump will pump more and may be able to overcome...

    First Tohatsu motor 9.9HP

    Ha! Oops, tired brain, forgot we were talking about a 2-stroke. But valves still apply, check out the reeds (reed valves), stock ones are usually metal, make sure they're not bent or dirty and that the surface they seal against is clean and flat. The rest still applies I believe. Also play...

    MFS6 flush

    The thermostat should open very quickly, within a minute or two where I live (ambient temps typically 70-90F, water from the hose probably 70-ish). Especially if you run it a little above idle. This goes for both my little Tohatsu 6HP and my Honda 50HP. You can tell when it opens by the...

    Converting Tohatsu 5hp to 6hp (4 Stroke) returns disappointing results.

    Around here you have to reel fast or you'll likely get cut off, or stolen by a shark. ;) With such small motors and such big swings in how the boat is loaded with a small jon boat, IMHO it's going to be difficult to split hairs on the prop. For example, say you're turning 6200rpm just you; add...

    2008 Honda 75HP EFI outboard challenge

    Try running it off of a small portable tank with a short gas line. If that works fine then start checking the main line for leaks, or maybe the in-tank screen is clogged, etc..

    engine oil drains very slow

    In case it's not too late, when re-filling the gearcase, remove both the top and drain plugs, attach the oil pump to the drain plug and fill it from the drain plug.

    Honda 225 outboard impeller question

    There's no telling what's wrong until you take it apart and look. Did you use OEM parts, or aftermarket? OEM are usually the best quality.

    2012 Honda 15 HP (Water not Peeing at Idle)

    Check the thermostat, make sure it's not stuck open. When you changed the impeller, what did the cup and the wear plate look like? Were they smooth and flat, or did they have any groves in them?

    First Tohatsu motor 9.9HP

    It sounds like you're down to tuning. I would go back over all the basics. Make sure the valves are properly adjusted, overly tight valves can cause idle problems. Also make very sure the pilot circuit in the carburetor is spotless. Sometimes there are tiny holes that need to be cleaned. If...

    Converting Tohatsu 5hp to 6hp (4 Stroke) returns disappointing results.

    The carburetor quality can make a big difference in performance, my guess is the aftermarket won't be as good as OEM. Just to give you a data point, I've got a 6HP Tohatsu on an old 13 or 14' Duracraft flat bottom jon boat. The boat probably weighs 100#. With just me (165#) I believe it does...

    BF45: removing oil pan?

    Those exhaust pipes are totally different. If the pans are the same, I would use the new pan with the old exhaust pipe, assuming the old pipe is still in serviceable condition.

    2001 Honda BF50 rev-limiter question

    You can get an hour meter + tach on Amazon for around $20, you can't watch it while you're driving but afterwards it will remember the max RPM and you can check to see how high it went. That said, you can overrev with a prop in my experience. I've got a 99' 50 on a 17' Boston Whaler Montauk...

    BF50A Stiff Shift

    If you need to loosen up or remove old grease, WD-40 is excellent. For example, if the steering cable tube gets stiff from old grease, liberal WD-40 and a stiff bottle brush on a drill will have the old grease out in a snap. You can flush the cable with it too if you've got a way to push it...

    Impeller overheating

    There are 3 water intake vents; one on each side of the lower unit, PLUS one on the bottom of the anti ventilation plate just above the prop. You've got use ears that flow enough water that you have water pouring from that vent over the prop. Alternatively you can block that vent with tape...

    Removing wax marks from gelcoat

    Thanks guys for the replies. The captain hired a pro to go over it so we're all good. It's a 68' boat so there was a lot to do. Fortunately the captain realized he didn't give any instructions and the wax he gave my son is not good in the sun, so it appears there are no hard feelings.

    Overheating

    I've got a 50HP Honda I bought new in 99' and have run it on muffs after every use, and in a garbage can several times, no problems at all. If on muffs you have to be sure there is enough water flowing that it's also coming out the vent that is under the anti ventilation plate. In the bucket...

    Removing wax marks from gelcoat

    What is the easiest way to remove dried wax marks from gelcoat? My 16yr old son has been working at our local docks as hired hourly help and a captain hired him to wax a very expensive sport fishing boat, unfortunately the captain handed him a bottle of liquid non-cleaner wax and said go to...
