    initial boat inspection how to's

    One thing to keep in mind is that the engine is 21 years old, raw water cooled, and has been run in salt water. The exhaust manifolds and risers can be (and usually are) replaced on a 5-7 year interval in salt water, but the engine block is not easily replaced. You will certainly get more...

    Signs of bad pour foam

    I don't really get carried away with mixing tools for pour-in foam, You only get about 20 seconds to mix it :oops: , so even a paint stir stick will do. Also, it is best to mix in small batches according to how much you can pour in about 30 seconds.

    WOT RPM too high. Where is the slip?

    Things to check/verify . . . Tachometer giving correct RPM reading (does the engine really sound like it is revving to 5K ?) Outdrive trim - is the trim reading (sender/gauge) off/inaccurate? Bravo 3 prop blades bent, dinged, etc ? (and yes - no hubs on a Bravo 3) Clutch? 🤪

    Cracked block leaking water

    Looks like the JB-Weld fairy has already been there fixing the cracked block. With obvious patches visible and signs of water seepage from the lower part of the engine block, why would you think the block is not cracked ? :rolleyes:

    Dual johnson 6hp outboard on boat

    In theory . . . Change in speed is not a linear relationship to change in power. Power = Force x Velocity Doubling the power may get about a 30% increase in speed. If the boat has a fairly flat bottom towards the stern, it may help.

    Volvo Penta won’t run at full power

    Welcome to iBoats. . . Short answer is yes. The first thing to check is the venting of the fuel tank, as it may be clogged. See if the problem goes away if you loosen the fuel fill cap slightly so air can get in. If so, then check the vent line to the tank for clogs, kinks, other obstructions.

    Risers and manifolds at the same time?

    My Formula 330 had the SS risers (elbows) and the iron manifolds, with closed cooling. So the coolant ran through the manifolds and the sea water ran out the SS risers . . . worked great and lasts forever (ie a long time)

    Potential project boat

    Agree with the others, I would expect to find a fair amount of structural rot making a full gut and rebuild the right thing to do. If you take this on, make sure the current owner has the NY state title in hand as you will want/need it to take proper ownership of the boat. (else you won't be...

    1992 (ish) Evinrude 25 HP Remote Control Repair/Replacement

    Thank you. Is there any chance that a new BRP control box would work if there are adaptors for the round vs. square plugs? or are there complexities to consider?

    1992 (ish) Evinrude 25 HP Remote Control Repair/Replacement

    I was going to place this thread in the 'Steering & Controls' forum, but thought the Evinrude/Johnson forum might get a bit more traction. :unsure: Anyway. My 13 foot Boston Whaler with 25 HP Evinrude OB (short shaft) is in need of some control box refurbishment or replacement. I'd like to...

    Risers and manifolds at the same time?

    There will be either raw water or coolant in the exhaust manifold. A FULL Closed Cooling system will have coolant in the manifolds. HALF Closed or RAW WATER Cooling will have the ocean/lake water in the manifolds. So, if you are running a Raw water or Half closed system (in salt water) there...

    WOT for 20min and engine bogs.

    So, your friend is running at WOT for 20 minutes? or is it just after 20 minutes of running the engine bogs down and won't throttle up?

    4.3L Mercruiser Milkshake

    Scales of rust flaking off the cylinder side walls reducing its thickness and eventually the pressure inside the cylinder breaks the weakened area. First example that I've seen happen, but it certainly can & does. that is one of the reasons why raw water cooled engines in salt water have a...

    Exterior vs interior plywood

    Why? Because, that's why :ROFLMAO: Actually, you want the plywood to have little/no chance of delaminating. Fiberglass/resin encapsulated wood does absorb moisture (water) over time and the higher levels of moisture could lead to ply separation.

    1990 Bayliner 2651 resto

    You may want to get an idea of how long (front-to-back) the fuel tank is in order to judge if the tank will come out via the engine bay by pulling it back once the bulkhead is cut. Worst case is having to cut away part of the aft berth base & bulkhead to gain the clearance needed.

    Lighting questions - Chaparral 347 SSX

    You had a 327 and then upgraded to the 347 ??? Basically the same boat except a bit more swim platform (right?) I don't recall exactly what brand/model, but they may have been 'ITC' brand 'tricolor' LED - water resistant. (about $44 on Amazon) I had to pry off the stainless steel bezel...
