View Full Version : Prop Guard - 87 Prostar 190 Trailer

I'm the 3rd owner of a 87 MC PS 190 trailer. The trailer does not have a prop guard, and looking at the documentation from the previous owner, the trailer was refurbished at some point. Today I came across an 89 ProStar sitting on an identical trailer that had a bolt-on prop guard.

1. Were these prop guards an option on the trailers?

2. If not, I can assume the previous owner removed the prop guard.

3. Does anyone know where I might find a bolt on prop guard?

Thanks,

Shane

I don't think there is a "kit" available to add a prop guard to a trailer, you will most likely need to have one fabricated at a local welding shop. Take some google pics with you do they can see what you want, and while your at it have them add some caster wheels on the edges so the new guard won't get concrete rash and drag, I do believe there are caster kits available. If not I do know that several TT members have added wheels maybe they can chime in...

I think the prop guard was offered as an option. My '87 trailer did not have one either. Should be a pretty easy job for a fab shop, but I would personally just go without. Never had a problem with the '87, and our current '84 doesn't have one either and we've never had a problem with it. You need some pretty steep or uneven ground to make contact with the prop.

I'll check with a local shop to see what they can do re: missing prop guard, I already have some casters and I always wondered why trailer companies didn't add these. I remember scraping my prop guard with my previous boat which was a 92 Hydrodyne Inboard Comp.

I'm taking the trailer to a local shop tomorrow to add a vertical post w/roller stop and platform to bring the winch level with the bow ring. I'm not adding the Boat Buddy because the ramps I use are very steep and ultimately it would put too much strain on the pin. I know there are folks who favor using the original bar for safety, but I can accomplish the same with a shackle or large guage chain and transom tie downs for the rare occasion when I tow the boat out of the neighborhood. The potential of losing a finger or getting pinched when using that bar is just too high as I rely on the wife and kids to secure the bow when loading on steep ramps.

I bent a newly re-conditioned prop last year, but did not notice it till we got home. It is possible I may have drug it over a large rock at our ramp. I had to remove some very large boulders 12" - 14" that had obviously been placed there intentionally.

I would think the price of the prop-guard would be about the same as one prop replacement. Seems like an easy expense to justify.

Do you have a Mastercraft Trailer? I can get you some dimensions and pictures from my '88. I'd be glad to help, I'll be under it tonight hooking up the fake a lake.

.......... I'll be under it tonight hooking up the fake a lake.There is an easier way. Pull the intake hose from the top (vertical position) of the transmission cooler. Feed it with a water hose from there. Much easier.

You can build one out of tube steel or channel iron.

Thanks, I was able to locate a pdf file on one of these threads that had dimensions. Headed to the fab shop today :)

Moving the winch higher is a great idea. It hasn't happened yet, but I loathe the day I can't drive the boat on the trailer, 'cause it ain't coming on there with that OEM low-mounted winch. I still used the bar, but agree that a bow chain and transom straps would do the same thing. FWIW I have the original prop guard, it's OK but someone could make something much beefier pretty easy and adding casters is the way to go.

Still working on solution to add a prop guard. In the meantime, I had the local fab shop re-work the winch and bar locations on the trailer.

Nice work on the winch stand.

The rudder on the 84 was pitted very bad.

Thanks for all the help here. Race City Steel here in Denver, NC will fab my prop guard next week using 1/4" x 3" flat bar.

I need to replace the stock rims/tires on my MC trailer and I'm considering moving up to a 15" rim/tire combo for a little additional clearance (prop/prop guard/ground). Of course this means less clearance between tire and fender. Has anyone here moved up to a larger rim/tire on the stock MC trailer with fiberglass fenders?

First thing to know is while wheel measurements are standardized, tires specs are not. Each manufacturer has slightly different measurements. Things also start interesting when you consider as you increase wheel diameter, you typically increase wheel width. I needed a little more clearance as my propguard was hitting at the entrance to my driveway. I went up one size in tires and that worked fine as I had the clearance to go taller, but not wider.

I am running 16*7 rims with 225/60/16 tyres. Things are tight for clearance mind you. Just ask your tyre fitter for outside diameter of different tyres and see what he comes up with.BTW 1/4" may be a touch thin for your guard. Have fun.

Fab shop actually has 1/2" by 3" flat bar, so I may move up to that, but I'm assuming that will mean cuts and welds vs bends.
