I am looking at an 87' Rinker V170 with a Mercruiser 120, the lower unit has just been rebuilt and the engine runs smooth. I did a compression test on it today and its showing between 110 and 120 pounds of pressure. When i pulled the spark plugs out they one of them had gas on it the boat had been sitting for about 3 years covered up and the plugs looked old. He is asking $1,000 for it and he is a really good friend of mine. What do you think does it sound like a decent deal or not.

Re: Looking at a boat

well?

Does the motor run?


Why buy a boat for a grand that may need 15 grand in repairs when you could just by a new one or buy my 07 bayliner 185 lol.....

Seriously

the 120 is a pretty good little motor and for a 17 foot boat it will do a good job and be good on gas as well. But does it run? and How does it run is what you need to know to know if investing a grand would be worth it.

Boats that sit that long could be money pits. Could the block be cracked from not winterising correctly? Who knows.

It needs a water pump impeller, oil change....Drive pulled and check bellows and gymbal bearing. Drive oil change....A lot needs, fuel filter (if applicable) changed to happen before its ready to go back in the water.

Re: Looking at a boat

Yeah he started it up and it ran very smooth, smoother than most cars run. It has been covered up the whole time. Its never been dry docked and has had the fluids changed on time. Its my first boat and im trying to get any help i can. He said if theres anything that needs to be changed it might be the impeller but he doesn't even think that needs to be changed. It is a really good freind of mine and i don't think he would lie to me.

He probably would not lie to you. But he probably doesn't know any better.

An engine that has sat for 3 years NEEDS a new impeller. When they sit, the vanes bend and dry out. I would also replace the bellows. Old rubber is not a good thing. Fuel sitting in a carb for that time is not good either, but it sounds like he treated it.

Before shelling out that $1K, I would look REALLY close at the hull, deck and transom. What good is a running engine when the stringers are mush?​

boat regardless. nobody sells a good engine for that much unless they really need so dough. and fyi since this is your first, boats cost big big $$ to use and maintain annually.

Take an ice pick and poke around the transom and stringers it shouldn't go in far.It sounds like the is giving you a good deal.I have bought running boats for 500$.
fixB52's is right change the impeller,and the gear oil.Then change the oil in the motor. That motor should last a long time.Jerry

Re: Looking at a boat

I'm sure he wouldn't lie to you as a friend, but as stated he may not know any better. the statement on the impeller is a give away. Maintenance on this beast is gonna be suspect. Anyone who knows about boat care knows an impeller will take a set after sitting that long, and even if not they need replacing every couple years. SO who know what else he thinks is "OK"

For a grand you can't go wrong if the transom and stringers are ok and the engine runs, but it's gonna need work very shortly. You are gonna take it out and be back after after the first few outings with a post like "It ran great and then..."

The worst thing that a boat can do is sit. As soon as you start using it the gremlins will rear their heads

If you are up to the challenge go for it. But all the mechanical systems are going to be at risk. From rusty gimbel bearing to rusted light switch. Bad gas or gummed up carb. It's all there waiting for you..

And for the record, I am looking for just such a boat to use on lakes, so I am not saying don't do it, just be prepared for what awaits you. Most of us bought our first bought in very similar ways and we all went through the same thing when we did

One thing you will want to do is pull the risers and check the manifiold and riser conditions. There are too many sad stories of overheats and burning up engines right after newbies bought boats.

Good Luck!

Re: Looking at a boat

Did you take it for a test run? make sure you will be happy with the performace. Also, buy a new bidge pump, chances are the one in there is worn, less efficent, or broken. Buy one with an auto switch.
