Hello all,

For the second Summer in a row.. I am having issues with my 1993 Mastercraft Prostar 190. The boat runs and drives fine on initial start up, but it WILL NOT hot start. Once it has ran for at least 30 minutes all it will do is crank, crank & crank.

- 351 indmar engine
- New plugs
- New wires
- Ordering a new distributor cap today
- Holley carburetor

EDIT. Please review our rules.

this is only my 2nd season as a boat owner. i dropped my boat in the water for the first time since it's winter hibernation this past weekend and apparently i didn't know i was supposed to check for the plug. during my 100 hour maintenance & dewinterization 3 weeks ago the plug was removed. i realized the boat was very low in the water in the back while backing it off my trailer. it was like this for approx 5 minutes. it wasn't until i opened the engine compartment on my 2007 Moomba Mobius LSV that i realized there was a significant amount of water in it. i pulled the boat back on the trailer, drained it, put the plug back in, backed off the trailer and it started up just fine.

we ran the boat for approx 1 hour, then dropped anchor in the lake, turned off the engine and relaxed for 30 minutes. when i went to turn the key NOTHING happened. no alarm noise, no engine sound (didn't even sound like it was trying) NOTHING. after 30 more minutes of trying everything i could think of the boat magically started??

fast forward to this weekend....boat started up fine. we ran it for an hour. dropped anchor and it sat with NO engine running for ~45 minutes. turned the key, started right up just fine. we ran the boat for another 30 minutes, then anchored again. this time the boat's engine was turned OFF for ~2 hours. then, when i turned the key this time the engine sounded like it wanted to start, but wouldn't (almost like fuel wasn't getting to it). after many attempts it finally did the same thing it did last weekend....with each turn of the key, no sound, no NOTHING.

during both of these incidents the stereo worked, the bilge worked, the blower worked, all power worked except the engine?? i can't figure it out but must think it has something to do with the flooding of the engine when i attempted to back the boat in the water with the plug out. any help would be greatly appreciated.

thank you!

So I am trying to pull the harmonic balancer and was going to use a breaker bar but after reading a bit it sounds like an impact is the way to go. My question is if my engine is reverse rotation would the center bolt on the balancer need to spin the opposite way of engine rotation to come off? Any tools I can use to stop the engine from spinning when doing this?

Hey all,

Does anybody have any suggestions as to how I'm suppose to change the oil w/ this motor? I have been searching (basically feeling) around for the oil drain plug on this motor and I can't find it. Once, I do find it, how am I suppose to drain the oil when there's only a 6in gap? Is there a way to siphon the oil out or something?

Here's a pick of the engine:

Just wanted to get something off my chest. I've been biting my tongue for quite a while. I will get phone calls to my shop wanting to speak to me concerning the Yamaha Sterndrives. Many of these calls start off with, I just bought a bunch of parts and I need advice on installing them. My first thought is, you didn't buy them from me so why are you asking me? Ask the shop you bought them from. But I've yet to actually blurt that out but I've come close a few times.
So before you phone me and take me away from a boat that I'm upside down in, think about what you are going to say. I don't mind helping folks out but I'm in the business of selling parts and repairing boats.
OK, I'll quit beating that horse now.

The Yamaha throttle/shifter on my old Hurricane deckboat can be a bit difficult at times,can it be lubed? Note the small orange plug on assembly..Thanks..Jon

another question is if i remove the 2 set screw bolts in the flange on the drive shaft to the transmission will the drive shaft pull out to the back of the boat so that i can change the rubber hose that connects the stuffin boxs

Thanks Bob

Dont know if this is the right forum but Im buying my uncles mastercraft stars and strips boat that has been in storage for 4 years and wanted to know what I should do to it to get it running? All I know about it is that it has a 351 ford motor in it.
Thanks Guys for any help

Hey all I have a friend that has a port engine that is having starting problems. Let me embellish a little, they call it a crusader 220, looks like a Chevrolet 305 or 350 to me. Going to look for myself tomorrow but I wanted to throw this out there. No start, brand new started, just the starter clicks "loudly" and again this is all word of mouth. I'm think either bad teeth on the fly wheel, bad voltage/amperage or new starter is junk. Any insight?

I just purchased a 1997 Regal Rush XR2 boat, it has not run in at least 2 years. I went online and purchased the service manual for it and have read a little about this boat. I have owned outboards before but not like this, I need to know if these boats have any common problems and what I need to check or do when I first start this thing up. Someone has wired a new ignition switch to this thing, but I have the original also. I don't know if it runs or not because I purchased it from a third party after the boat was abandoned. Thanks for any help on this issue.

I have a Chrysler m46 in my Chris craft and I'm having oil issues. I have a lot of oil leaking out of the exhaust pipe while running. I do have good oil pressure. I did a compression test and found that all cylinders have between 70 to 110 lbs of compression. The engine will run with full choke on but when I take it out of choke the engine will race out of control to a much higher rpm. I took the head of yesterday and inspected the gasket and cylinder walls. I also poured some marvel mystery oil down and let it soak down to the rings. I am at a loss for what could be causing this problem. Any suggestions would be great appreciated. The engine will start quite easily with a turn of the key.

Guys- I had this problem last year too but when I start the (5.7l) engine, I have to wait until it warms up to put it into reverse for 5 min or so or it dies. Not that big of deal on a slow day at the ramp but when it's busy....well.

I had the carb and choke adjusted by a good mechanic last year as the previous owner had obviosly played around with the carb. The idle adjustment mix screws were all screwed up and the choke was adjusted so bad that it wasn't even engaging. All of this was fixed and it ran really good last year. I just think that unless conditions are perfect (like brand new gas and high temps) it just doesnt have quite enough RPM's at cold idle to overcome the load at startup when engaing the gears. What can I do? The boat otherwise runs great when warm. carb is a Holly 4150 600cfm.

Hello I have a 32foot luhrs i just bought its still on land but i need to change the packings before putting her back in the water any advice on changing them would be a great help the rudders seem to be ez to see but the driveshafts are in the back & ubder the transmissions looks tuff to get to. any help before I start would be appreciated, tools packing material etc. anything I may run into problems Thanks Bob

i have a 1995 marine power 350 with the est distributor, it runs bad and smells of gas when idling. top in not good either and fouls the plugs. i have set the timing right and have the plug in wire to set it but it still runs really bad, i took a unilite distributor out of one of my other motors and now the boat is running perfect. do they make and aftermarket module for the est dist. or what could possibly be wrong with that dist. i did replace coil as well when installing the unilite dist.

Hi, I am posting this on behalf of my boyfriend and we are both fairly inexperienced with boat mechanics. We tried to start the boat up for the first time since the winter and are having issues. When turnin the key power is being received by the stero, fish finder, leg lifts but it won't turn over or start. Also the negative on the battery gets really hot and begins to smoke/ spark. We have cleaned the battery posts, terminals etc and no luck. Not sure what to try next as we have googled the problem and seems like there could be many seperate issues causing the problem. Can anyone suggest what we could check next to narrow it down or anyone have had this issue themselves? Thanks in advance.
