In their fifth pre-season friendly, United cruised to a 5-0 victory over Cumnock Juniors.
First half goals from Michael Donald and Alan Forrest gave Ayr a comfortable lead before Moffat, Marenghi and McGowan put their names on the score sheet.
Mark Roberts started Josh McArthur as a trialist alongside Alan Lithgow and Alan Forrest made his first start for the club, working alongside Michael Moffat up front.
Martyn Campbell was also involved in the squad after suffering from injury last season and played the last half an hour of the match.
Ayr United started the game brightly with shots from Crawford, Forrest and Moffat showing early signs of intent.
United took the lead on the 21 minute mark after 16 year old Alan Forrest saw his thumping shot saved by the goalkeeper but Michael Donald was on hand tap home.
It wasn’t long before Ayr doubled their lead seven minutes later when Michael Moffat crossed to Alan Forrest who was able to head the ball into the net, notching his first goal for The Honest Men.
With 33 minutes on the clock, United were awarded a penalty but Michael Moffat saw his spot kick saved by former Ayr trialist, Ally Semple.
Ayr were never under any pressure from Cumnock and after 73 minutes the floodgates opened with Michael Moffat winning his second penalty of the game and coolly dispatching it into the top corner.
Two minutes later, substitute, Anthony Marenghi stepped up to take a free kick 28 yards from goal and wickedly whipped the ball beyond Semple.
With the game drawing to a close, Mark Shankland tried his luck from long range before Mikey McGowan completed the rout after a neat interchange with Adam Hunter.
Post-match, an upbeat Mark Roberts said: “I asked the boys to go about the game in a professional manner and they did that. Our fitness levels and performance were excellent and we could have won the game by another four or five goals.
“The game was very beneficial for us as I think the guys are now ready for next week’s Challenge Cup game against Queens Park.
“Martyn Campbell returned from injury but it’ll take him a few weeks to be back to full fitness.
“Alan Forrest started the game and was excellent. He is a livewire and was very clever throughout.
“Malcolm and Moffat are our main two strikers but Forrest is a guy that can come on and cause defences problems.
“I trust the guys in our team to do a job for us. I’m not going to moan about budgets as I think we have brought in some really good players who will do well.
“Josh McArthur started the game as a trialist and will sign on Tuesday. He is 17 but he will play this season as he’s a talented player.”
After scoring his first goal for Ayr United, Alan Forrest beamed: “I really enjoyed today’s game. To start the match was very special as I wasn’t expecting it. To score just topped off the day for me.
“I started up front today but I can also play in the wide areas.”
The 16 year old impressed throughout the game and pulled off several tricks that his brother, James, would have been proud of.
Forrest said: “My brother James plays with Celtic and has been giving me lots of advice. He comes and supports me when he’s got time off which is massive boost.”
