See full version: Ear muffs to flush yamaha 40hp? Nothing fits
I have a 3 cyl 2 stroke. The water intake is shaped so that the muffs dont get a good seal, they kind of taper into the metal, so the water just gets pushed out the front toward the transom. Subsequently i get a trickle when flushing unlike when In the ocean.
yeah i know the wheely bins you mean, wish i had one of those, i know what it would be used for. taking the foil on and off each week will be too much hassle. dont have a lake anywhere within 400km. ill have to be creative i guess. i thought it would fit in our garbage bin as our old outboard did but no way with the hydrofoil. not a lot of resources around here for getting big drums either. more
interestingly it spits water out the holes just above the water intake fine, but only lightly streams from the top hole with the muffs. more
So just bought a used boat, and noticed that the tell tale is not coming out as it drips when using the water hose. Took it into my local mechanic and recommended water pump and thermostat replacement. He's done those things now and says engine is still overheating. He has called me back to say that water is not getting into the engine and suspects that he will have to take apart the engine which is to the tune of potentially about $1500 to $3500 to take apart and put together or I could just call it a day and post it with the issues. He said engine itself is fine, compression etc all checked out minus overheating.
Not trying to pile on here but it appears you've already committed to being the fool for buying a motor without water testing. I know that's harsh and you're here looking for help. but always good to acknowledge the reality of the situation, ya know. The cooling system might be just the 1st of many issues. more
If you're paying someone else to handle quite simple maintenance installations as the water pump and stats then be prepared to continue dumping money into service labor costs. Maybe cut your losses and sell for parts. Otherwise, get yourself a model/year specific service manual and dig in. more
Any info is greatly appreciated. more
Hello All, I have a question and just couldn't wait for the dealer to open tomorrow. I just recently repowered to a brand new 2017 Yamaha F150XB. I picked it up from the dealer yesterday. I went in, walked the boat, inspect the engine rigging and mounting, went over break-in procedure with sales guy and that's it. We did not do a start up test at the dealer. Today I finally got around to starting it up home to make sure all is well before heading off to the water this weekend for some crabbing and begin the break-in process.
Side note about dealership personnel. most of whom you speak with are not marine mechanics, rather salespeople. So take what they say with a grain of salt. I recommend registering on the www.yamahaoutboardparts.com website. There are a number of yamaha marine mechanics who are members and will answer questions. You can also search through threads pertaining to your question and find more info than I've given. Good luck. [links]
Water pressure from your spigot will also effect the engines TT. If low pressure, expect very little water to exit TT. So long as the water pump is receiving a healthy amount of water to pump through the engine you should not be concerned of over heating the engine. here
